Abstract:
An individual in vitro culture system for bovine embryo needs to be developed for the study of embryo developmental competence. The objective of this study was to examine the effect of individual culture systems on the development of in vitro-matured–in vitro-fertilized bovine embryos. Two individual culture systems were compared. Cumulus–oocyte complexes (COC) were collected by aspiration of ovarian follicles (diameter, 2 to 5 mm) obtained from a local abattoir. The COC were matured in TCM-199 supplemented with 5% calf serum and 0.02 AU mL–1 of FSH. Groups of 20 COC were incubated in 100-μL droplets of IVM media at 38.5°C under an atmosphere of 5% CO2 for 20 h. After 18 h of gamete co-culture (3 × 106 sperm mL–1), the presumptive zygotes were cultured in CR1aa medium supplemented with 5% calf serum at 38.5°C under an atmosphere of 5% CO2, 5% O2 and 90% N2 for 9 days (fertilization = Day 0). The presumptive zygotes were randomly assigned to 1 of the following 3 treatments: single culture (1 zygote was cultured in a 5-μL droplet), well-of-the-well (WOW; Sugimura et al. 2010 Biol. Reprod. 83, 970–978) culture (25 zygotes were cultured individually in each 125-μL droplet) and control culture (25 zygotes were cultured in a 125-μL droplet). Embryo development was evaluated for cleavage and blastocyst rates, on Day 2 and Day 7 to 9 after IVF, respectively. The rates of development up to the blastocyst stage and total cell number in the blastocysts, determined by an air-drying method, were investigated. The cleavage and blastocyst rates were analysed by the chi-square test and the total cell numbers were analysed by ANOVA. The cleavage rates were significantly higher in the control and WOW groups than in the single-culture group (P < 0.01) and the blastocyst rates were significantly lower in the single-culture group than in the control culture group (P < 0.05; Table 1). The total cell numbers (mean ± s.d.) of blastocysts did not significantly differ between the single culture (154.6 ± 21.8), control culture (155.2 ± 22.5) and WOW culture (159.8 ± 27.0) groups. These results indicate that although the blastocyst rate was lower in the single-culture system than in the WOW or group culture system, in vitro-matured–in vitro-fertilized bovine embryos can be cultured using the single-culture system. Moreover, the quality of blastocysts developed by the single-culture system is the same as that of blastocysts developed using the other 2 culture systems.

Abstract:
Entomopathogenic nematodes (EPNs) have been successfully applied as biological control agents against above ground and soil stages of insect pests. However, for commercial application, it is crucial to mass culture these nematodes using in vitro liquid culture technology, as it is not attainable when using susceptible insects as hosts. Lobesia vanillana (Lepidoptera: Tortricidae) is regarded a sporadic pest of wine grapes in South Africa. The in vivo- and in vitro-cultured South African EPNs, Steinernema yirgalemense and Steinernema jeffreyense (Rhabditida: Steinernematidae), were evaluated against larvae and pupae of L. vanillana in laboratory bioassays. For larvae, high mortality was observed for all treatments: In vitro-cultured S. yirgalemense (98%) performed better than S. jeffreyense (73%), while within in vivo cultures, there was no difference between nematode species (both 83%). No significant difference was detected between in vivo- and in vitro cultures of the same nematode species. The LD50 of the in vitro-cultured S. yirgalemense, was 7.33 nematodes per larva. Mortality by infection was established by dissecting L. vanillana cadavers and confirming the presence of nematodes, which was > 90% for all treatments. Within in vitro cultures, both S. yirgalemense and S. jeffreyense were able to produce a new cohort of infective juveniles from L. vanillana larvae. Pupae, however, were found to be considerably less susceptible to EPN infection. This is the first study on the use of EPNs to control L. vanillana. The relative success of in vitro-cultured EPN species in laboratory assays, without any loss in pathogenicity, is encouraging for further research and development of this technology.

Abstract:
Osteogenic differentiation of osteoprogenitor cells in three-dimensional (3D) in vitro culture remains poorly understood. Using quantitative real-time RT-PCR techniques, we examined mRNA expression of alkaline phosphatase, osteocalcin, and vascular endothelial growth factor (VEGF) in murine preosteoblastic MC3T3-E1 cells cultured for 48 h and 14 days on conventional two-dimensional (2D) poly(l-lactide-co-glycolide) (PLGA) films and 3D PLGA scaffolds. Differences in VEGF secretion and function between 2D and 3D culture systems were examined using Western blots and an in vitro Matrigel-based angiogenesis assay. Expression of both alkaline phosphatase and osteocalcin in cells cultured on 3D scaffolds was significantly downregulated relative to 2D controls in 48 h and 14 day cultures. In contrast, elevated levels of VEGF expression in 3D culture were noted at every time point in short- and long-term culture. VEGF protein secretion in 3D cultures was triple the amount of secretion observed in 2D controls. Conditioned medium from 3D cultures induced an enhanced level of angiogenic activity, as evidenced by increases in branch points observed in in vitro angiogenesis assays. These results collectively indicate that MC3T3-E1 cells commit to osteogenic differentiation at a slower rate when cultured on 3D PLGA scaffolds and that VEGF is preferentially expressed by these cells when they are cultured in three dimensions.

Abstract:
The aim of the present study was to investigate the effects of activin-A and follistatin on in vitro primordial and primary follicle development in goats. To study primordial follicle development (experiment 1), pieces of ovarian cortex were cultured in vitro for 5 days in minimal essential medium (MEM) supplemented with activin-A (0, 10 or 100 ng/ml), follistatin (0, 10 or 100 ng/ml) or combinations of the two. After culture, the numbers of primordial follicles and more advanced follicle stages were calculated and compared with those in non-cultured tissue. Protein and mRNA expression of activin-A, follistatin, Kit ligand (KL), growth differentiation factor-9 (GDF-9) and bone morphogenetic protein-15 (BMP-15) in non-cultured and cultured follicles were studied by immunohistochemistry and PCR. To evaluate primary follicle growth (experiment 2), freshly isolated follicles were cultured for 6 days in MEM plus 100 ng/ml activin-A, 100 ng/ml follistatin or 100 ng/ml activin-A plus 200 ng/ml follistatin. Morphology, follicle and oocyte diameters in cultured tissue and isolated follicles before and after culture were assessed. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL) reactions were performed to study DNA fragmentation in follicles. In experiment 1, it was found that goat primordial follicles were activated to develop into more advanced stages, i.e. intermediate and primary follicles, during in vitro culture, but neither activin-A nor follistatin affected the number of primordial follicles that entered the growth phase. Activin-A treatment enhanced the number of morphologically normal follicles and stimulated their growth during cortical tissue culture. The effects were, however, not counteracted by follistatin. The follicles in cultured goat tissue maintained their expression of proteins and mRNA for activin-A, follistatin, KL, GDF-9 and BMP-15. Fewer than 30% of the atretic follicles in cultured cortical tissue had TUNEL-positive (oocyte or granulosa) cells. Activin-A did not affect the occurrence of TUNEL-positive cells in follicles within cortical tissue. In experiment 2, addition of activin-A to cultured isolated primary follicles significantly stimulated their growth, the effect being counteracted by follistatin. Absence of such a neutralizing effect of follistatin in the cultures with ovarian cortical tissue can be due to lower dose of follistatin used and incomplete blockage of activin in these experiments. In contrast to cortical enclosed atretic follicles, all atretic follicles that had arisen in cultures with isolated primary follicles had TUNEL-positive cells, which points to differences between isolated and ovarian tissue-enclosed follicles with regard to the followed pathways leading to their degeneration. In summary, this in vitro study has demonstrated that cultured goat primordial follicles are activated to grow and develop into intermediate and primary follicles. During in vitro culture, the follicles maintain their ability to express activin-A, follistatin, KL, GDF-9 and BMP-15. The in vitro growth and survival of activated follicles enclosed in cortical tissue and the in vitro growth of isolated primary follicles are stimulated by activin-A.

Abstract:
Several studies have demonstrated that in vitro culture of islets prolonged islet graft survival in immune-competent mice without administration of antirejection drugs. However, we recently showed that in vitro cultured microencapsulated neonatal porcine islets (NPI) were rejected in immune-competent mice not receiving antirejection therapy. The aim of this study was to determine whether culture of microencapsulated NPI in vivo could promote long-term survival of microencapsulated NPI in immune-competent mice without administration of antirejection drugs. Microencapsulated NPI that were cultured in vitro for 7 and 50 days or transplanted initially in immune-deficient C.B.-17 SCID-BEIGE mice for 100 days (in vivo cultured) were characterized and transplanted into streptozotocin-induced diabetic immune-competent BALB/c mice. Day 50 in vitro cultured and day 100 in vivo cultured microencapsulated NPI showed significantly higher insulin and DNA content, indicating maturation of NPI compared to day 7 in vitro cultured microencapsulated NPI. Interestingly, in vivo cultured microencapsulated NPI expressed lower levels of porcine antigens compared to day 7 and day 50 in vitro cultured microencapsulated NPI. Transplantation of day 7 in vitro cultured microencapsulated NPI did not reverse diabetes in immune-competent BALB/c mouse recipients. In contrast, transplantation of day 50 in vitro cultured and in vivo cultured microencapsulated NPI into diabetic immune-competent BALB/c mice resulted in the immediate reversal of hyperglycemia within 2 days posttransplantation. However, all recipients of day 50 in vitro cultured microencapsulated NPI eventually rejected their grafts by day 15 posttransplantation, while 6 of 10 BALB/c mouse recipients of in vivo cultured microencapsulated NPI maintained normoglycemia for 100 days posttransplantation. These results show that in vivo culture of NPI in immune-deficient mice results in the modulation of NPI, which allows for their long-term survival in immune-competent mice without antirejection therapy.

Abstract:
The role of silica and macrophages in fibrosis is well documented, but in bone formation it is relatively unknown despite decades of research with bioactive glasses. In this study macrophages were isolated from rat peritoneal and then cultured for five days in the presence of two types of silica microparticles with different solubilities. After the fifth day the culture medium was collected, purified and used as an additive in bone marrow derived rat stem cell cultures. The stem cells were cultured for five days in α-mem containing only 0,5% of FCS, enabling cell survival but disrupting their proliferation. As controls, stem cells were also cultured in α-mem containing silica microparticles. At days one and five the amount of soluble collagen was assayed from the culture medium and the cells were counted. All stem cell cultures with macrophage medium additives were found to be proliferative, with statistically significant difference to controls. However, collagen was only produced in cultures containing medium from macrophages cultured with fast-dissolving silica microparticles. This suggests that silica can induce cell proliferation and extra cellular matrix protein secretion which is mediated by macrophages, and that the solubility of silica is also a major factor in this reaction.

Abstract:
RAPD and phenotypic analysis were conducted to assess clonal stability of hazelnuts generated from axillary buds cultured in vitro for long-term. The nuts produced on in vitro-propagated plants were indistinguishable from those of donor plants. With the exception of rare horizontal (plagiotropic) growth, all in vitro-propagated plants exhibited phenotypes similar to those of donor plants. RAPD analysis did not reveal any somaclonal variation between donor plants from which in vitro cultures were initiated and micropropagated plants (6-year cultures), and no somaclonal variation was detected among in vitro-propagated plants. However, polymorphism (15.6%) was detected between the parent plant and its in vitro-propagated progenies (from seedlings). These results show a good discriminatory power of RAPD to detect polymorphism between samples where it is expected, and it can be effectively used for genetic assessment of micropropagated hazelnut. No evidence of genetic or epigenetic changes was observed in long-term cultured hazelnut, and thus long-term in vitro culture of hazelnut does not seem to limit its clonal propagation.

Abstract:
Nephropathic cystinosis represents a prototype for lysosomal storage diseases and is the most common cause of renal tubular Fanconi's syndrome. Mechanisms of the tubular transport defects in this disease have not been defined, however, in part because the cells readily cultured from affected patients, leukocytes and fibroblasts, do not express epithelial transport functions. Except for a single autopsy report, renal tubular cells from these patients have not been studied in vitro. In these studies, noninvasive harvesting and culture of renal tubular cells from the urine of patients with cystinosis is described. Cultures of renal tubular cells could be established from over 50% of the isolates which contained viable cells and which remained uncontaminated in vitro. Cells had an epithelial morphology in culture, and the majority of cultured cells expressed proximal tubular brush border marker enzyme. Cultured cells also expressed the storage defect in vitro, containing cystine levels up to 100 times those of normal cells. Cultured cells could be depleted of cystine by using the thiol cysteamine. This in vitro model system should be very useful for studying the mechanisms of renal tubular transport defects in this disease.

Leaves of wild apple (Malus domestica Borkh) were excised from in vitro grown shoots transversely cut into halves and plated onto petri dishes containing regeneration media. Cultures were kept in the dark for three weeks before adventitious shoots were observed. Callus from leaf explants produced adventitious shoots after 3 months of in vitro culture. Callus were cultured on Nitsch and Nitsch medium supplemented with a range of BA (0.0–2.0 μm) and NAA (0.0–10 μm). BA at 10 μm combined with NAA (0.5 μm) proved most effective for stimulating shoot proliferation of cultured apple. Plantlets from tissue culture were easily transferred to the greenhouse environment.

Abstract:
Fibronectin (Fn) is involved in the migration of epithelial cells in re-epithelialization of wounds. Epithelial cell-derived Fn is particularly potent as a chemotactic factor for bronchial epithelial cells (BECs) in vitro. Thus modulation of airway epithelial cell Fn may be a key aspect of airway repair. Insulin is both an important growth factor and known chemotactic factor for cultured BECs. We postulated that insulin may modulate Fn production of cultured BECs. We examined this hypothesis utilizing bovine BECs in culture with serum-free media with and without insulin. BECs grown in media without insulin released more Fn into culture supernatants and contained more Fn in cell layers than cells grown with insulin. Labeling of cells with [35S]methionine demonstrated an increase in new protein production and Fn mRNA expression was increased. Increased Fn in BEC cultures without insulin was associated with an increase in active transforming growth factor-beta (TGF-beta) release as measured by a standard bioassay. Increased BEC Fn in cultures without insulin was partially inhibited by exposure of cultures to TGF-beta antibody. Thus insulin appears to modulate BEC Fn production in vitro in part through a TGF-beta-dependent mechanism. Insulin may be involved in airway repair mechanisms through modulation of epithelial cell Fn production.

Abstract:
Previous research in bovine embryology has found that embryos cultured individually have limited ability to develop compared to their counterparts cultured in a group of other embryos. This investigation aimed to find if any of three different interventions over two experiments would increase development of individually cultured embryos to that of group cultured embryos. In the first experiment both the addition of serum/serum replacer and a co-culture with bovine granulosa cells were applied to individually cultured embryos in a 3x2 design. None of the interventions was found to be significantly different from the others, and all resulted in significantly lower development than embryos cultured as a group (avg. 4.7 +/- 1.93% individual vs. 21.7 +/- 3.76% group). However, a significant difference was found in the hatching rate between blastocysts cultured in media including cells (71.4 +/- 17.07%) and those cultured without cells (18.1 +/- 11.63%). In the second experiment, embryos were either cultured in standard droplets or microwells made at the bottom of culture droplets either in groups or individually for a 2x2 design. This experiment experienced poor development in all treatments including the group control, and none of the treatments were found to be significantly different from each other. However, the hatching rate of blastocysts cultured in multiple microwells was significantly higher than those cultured individually in droplets. To summarize, none of the treatments increased the development rate, but embryos cultured with granulosa cell co-cultures and in group microwells showed improvements in hatching rates.<br>Master of Science

Abstract:
In vitro testing includes both cell-based and cell-free systems that can be used to detect toxicity induced by xenobiotics. In vitro methods are especially useful in rapidly gathering intelligence regarding the toxicity of compounds for which none is available such as new chemical entities developed in the pharmaceutical industry. In addition to this, in vitro investigations are invaluable in providing information concerning mechanisms of toxicity of xenobiotics. This type of toxicity testing has gained popularity among the research and development community because of a number of advantages such as scalability to high throughput screening, cost-effectiveness and predictive power. Hepatotoxicity is one of the major causes of drug attrition and the high cost associated with drug development poses a heavy burden on the development of new chemical entities. Early detection of hepatotoxic agents by in vitro methods will improve lead optimisation and decrease the cost of drug development and reduce drug-induced liver injury. Literature highlights the need for a cellbased in vitro model that is capable of assessing multiple toxicity parameters, which assesses a wider scope of toxicity and would be able to detect subtle types of hepatotoxicity. The present study was aimed at developing an in vitro procedure capable of mechanistically profiling the effects of known hepatotoxin dichlorodiphenyl trichloroethane (DDT) and its metabolites, dichlorodiphenyl dichloroethylene (DDE) and dichlorodiphenyl dichloroethane (DDD) on an established liver-derived cell line, HepG2, by evaluating several different aspects of cellular function using a number of simultaneous in vitro assays on a single 96 well microplate. Examined parameters have been suggested by the European Medicines Agency and include: cell viability, phase I metabolism, oxidative stress, mitochondrial toxicity and mode of cell death (apoptosis vs. necrosis). To further assess whether the developed method was capable of detecting hepatoprotection, the effect of the known hepatoprotectant, N-acetylcysteine, was determined. Viability decreased in a dose-dependent manner yielding IC50 values of 54 μM, 64 μM and 44 μM for DDT, DDE and DDD, respectively. Evaluation of phase I metabolism showed that cytochrome P4501A1 activity was dose-dependently induced. Test compounds decreasedlevels of reactive oxygen species, and significantly hyperpolarised the mitochondrialmembrane potential. Assessment of the mode of cell death revealed a significant elevation of caspase-3 activity, with DDD proving to be most potent. DDT alone induced dosedependent loss of membrane integrity. These results suggest that the tested compounds produce apoptotic death likely due to mitochondrial toxicity with subsequent caspase-3 activation and apoptotic cell death. The developed in vitro assay method reduces the time it would take to assess the tested parameters separately, produces results from multiple endpoints that broadens the scope of toxicity compared to single-endpoint methods. In addition to this the method provides results that are truly comparable as all of the assays utilise the same batch of cells and are conducted on the same plate under the exact same conditions, which eliminates a considerable amount of variability that would be unavoidable otherwise. The present study laid a solid foundation for further development of this method by highlighting the unforeseen shortcomings that can be adjusted to improve scalability and predictive power.<br>Thesis (PhD)--University of Pretoria, 2011.<br>Pharmacology<br>unrestricted

Abstract:
In vitro production of embryos from oocytes recovered by laparoscopic oocyte pick-up (LOPU) offers great potential for the propagation of genetically valuable animals. In turn, the application of these techniques to prepubertal animals presents added benefits in that prepubertal animals may supply a greater number of oocytes than adult animals. The aim of the present study was to evaluate the developmental competence of prepubertal and adult goat oocytes cultured in semi-defined media. The follicular response and recovery of oocytes via LOPU from hormonally stimulated prepubertal and adult goats were also assessed.<br>Oocytes were collected over a 15-wk period from prepubertal goats, ranging in age between 3--7 mo, and adult controls, ranging in age between 2--4 yr, randomly divided into 10 collection groups. Oocytes from six of the ten collections were matured for 26 h. Four collections were not completed due to technical difficulties. Following insemination, zygotes were cultured for 4 d in G1.2 followed by 4 d in G2.2. Morulae and blastocysts were scored via light microscopy on Days 7 and 9, followed by fluorescent staining on Day 9 for cell counts. (Abstract shortened by UMI.)

Abstract:
In order to investigate vascular diseases such as cause of atherosclerosis and myocardial infarction, relationships of endothelial cells (ECs) covered with surface blood vessels and blood flow stimulation have been experimentally studied. In the study, a blood vessel model for in vitro experiment made from polydimethylsiloxane (PDMS) microchip with a straight microchannel with 400 μm width and 100 μm depth was developed. By optimizing cells cultured condition such as the liquid introduction method and the surface coating for enhancement of cell attachment on the microchannel wall, cell culture method in the microchip were developed. Velocity distributions on the ECs surface in the blood vessel model were measured using micro PIV technique. Measured velocity vectors on the ECs surface were fluctuated caused by the three dimensional effect of the cell shape.

Abstract:
The development of in vitro models is critical for furthering understanding of the intervertebral disc and the development of disc regeneration/tissue engineering. An in vitro culture system targeted towards mechano-biology studies of the intervertebral disc (IVD) was built and validated using bovine coccygeal discs. Discs were maintained in culture for up to one week with and without vertebral endplates. Water content and glycosaminoglycan content were found to be stable and cells were metabolically active when cultured under a 5kg static load.

Abstract:
A cell culture microfluidic device has been developed to test the cytotoxicity of anticancer drugs while reproducing multi-organ interactions in vitro. Cells were cultured in separate chambers representing the liver and tumor. The two chambers were connected through a channel to mimick the blood flow. Glioblastoma (GBM) cancer cells (M059K) and hepatoma cells (HepG2) were cultured in the tumor and the liver chambers, respectively. The cytotoxic effect of cancer treatment drug Temolozomide (TMZ) was tested using this two chamber system. The experimental results showed that with the liver cells, the cancer cells showed much higher viability than those without the liver cells. This indicates that the liver metabolism has strong effect on the toxicity of the anticancer drug. The results demonstrated that the perfused two chamber cell culture system has the potential to be used as a platform for drug screening in a more physiologically realistic environment.

Abstract:
The microvascular network is a simple but critical system that is responsible for various important biological mechanisms in the bodies of all animals. The ability to generate a functional microvessel in vitro not only makes it possible to engineer vital tissue of considerable size but also serves as a platform for biomedical studies. In this study, we propose a simple method for fabricating customized cylinder micro-scaffolds for the in vitro development of microvascular networks. By integrating micro-electro-mechanical systems techniques with thermal reflow, we design and fabricate a micro-scale hemi-cylinder photoresist template. Then, a replica mold of polydimethylsiloxane, produced by casting, is used to generate microvascular network scaffolds of poly(lactide-co-glycolide) (PLGA). We selected the human umbilical vein endothelial cell (HUVEC) as our model endothelial cell, seeded it onto both sides of the PLGA scaffold, and cultured it using a traditional approach with no pumping system. Results from fluorescent staining demonstrate that the scaffold was covered with HUVECs and that the desired microvascular network and pattern was generated in vitro. The proposed method enables the culture of cells on a scaffold using a conventional culture approach and allows continuous monitoring of cell conditions. The cell-covered scaffold can serve as a framework for building large tissues, while the formed microvascular network, after degradation of the biodegradable PLGA cylinder, can be used as the core of a vascular chip for in vitro circulation studies.

Abstract:
Synthetic vascular grafts are an integral tool in vascular surgery. However, the consistent failure of small diameter grafts is one of the main limitations of these devices. For this reason electrospun polyurethane has been investigated for its suitability as a vascular substitute material in this present study. Aligned and random mesh electrospun polyurethane materials were produced and analysed in vitro by investigating the effect of using both materials as a substrate for the culture of human aortic smooth muscle cells. Immunofluorescence analysis showed that cells cultured on electrospun polyurethane maintained a contractile phenotype to a much greater extent than those cultured on cast polyurethane membranes. This contractile phenotype is associated with the state in which a cell would normally reside in a healthy vessel, suggesting that electrospun polyurethane may provide a suitable vascular substitute material.

Abstract:
Traditionally, the interactions of drugs and toxicants with human tissue have been investigated in a reductionist way—for example, by focusing on specific molecular targets and using single-cell-type cultures before testing compounds in whole organisms. More recently, “systems biology” approaches attempt to enhance the predictive value of in vitro biological data by adopting a comprehensive description of biological systems and using computational tools that are sophisticated enough to handle the complexity of these systems. However, the utility of computational models resulting from these efforts completely relies on the quality of the data used to construct them. Here, we propose that recent advances in the development of bioengineered, three-dimensional, multicellular constructs provide in vitro data of sufficient complexity and physiological relevance to be used in predictive systems biology models of human responses. Such predictive models are essential to maximally leveraging these emerging bioengineering technologies to improve both therapeutic development and toxicity risk assessment. This brief outlines the opportunities presented by emerging technologies and approaches for the acceleration of drug development and toxicity testing, as well as the challenges lying ahead for the field.
