Les qualités des carcasses et des viandes/chairs des espèces d’intérêt agronomique (mammifères, espèces aviaires et poissons) dépendent en grande partie des caractéristiques et des proportions relatives des différents compartiments tissulaires, principalement les fibres et le tissu conjonctif musculaires et les tissus adipeux. Dans cette revue, nous décrivons la mise en place de ces trois compartiments au cours du développement embryonnaire et foetal, ainsi que leur croissance après la naissance ou l’éclosion.

Abstract:

Transferrin is an important growth-promoting serum glycoprotein synthesized chiefly in the liver in adults. The transferrin found in the mouse foetus is thought to be wholly a product of the foetus itself and its synthesis starts at least as early as the 7th day of gestation. The major sites of synthesis in mouse foetuses are the visceral yolk sac (VYS) and liver (Adamson, 1982). We now report that other murine foetal tissues synthesize readily detectable amounts, namely lung, spleen, spinal cord and rib cage. Very low levels are also synthesized by the brain, muscle and pancreas. We can detec

ABSTRACTThe concentrations of dry matter (DM), crude protein (CP), fat and ash were determined for 18 singleton red deer foetuses of known gestational ages within the range 72 to 224 days (term = 233 days) and for their associated placentae and empty uteri. In addition, concentrations of Ca, P, Mg, Na and K were determined for the foetuses. The amniotic and allantoic fluids were analysed for DM, CP and ash content.Concentrations of all measured components in the foetal fluids increased with foetal age (except for amniotic ash concentration which decreased) and linear regressions were fitted.

Abstract:

Nutrient intake during pregnancy affects foetal development and placental function in a range of species, often with long-term effects on offspring viability. Maternal nutrient supply is believed to affect the ability of the placenta to deliver nutrients to the foetus (Fowden et al., 2006). In ruminant species, the majority of placental nutrient transport occurs in specialised structures called placentomes, which are categorised into 4 types (A-D) based on their morphological appearance. In type A placentomes, maternal tissue surrounds foetal tissues, whereas type D placentomes are typically e

Abstract:

Androgens and anti-Müllerian hormone (AMH), secreted by the foetal testis, are responsible for the development of male reproductive organs and the regression of female anlagen. Virilization of the reproductive tract in association with the absence of Müllerian derivatives in the XX foetus implies the existence of testicular tissue, which can occur in the presence or absence of SRY. Recent advancement in the knowledge of the opposing gene cascades driving to the differentiation of the gonadal ridge into testes or ovaries during early foetal development has provided insight into the molecular ex

It is likely that in most tissues the high concentrations of lectin are largely due to increased synthesis by fibroblasts, which are particu

Abstract. Human decidua was found to synthesize and secrete placental protein 14 (PP14). The presence of PP14 in tissue explants of decidua, foetal membranes and placenta from term pregnancy was demonstrated by radioimmunoassay. The PP14 content in decidua (1300 ±410 ng/100 mg tissue) was higher than in chorion (570 ± 120 ng/100 mg; P < 0.01), amnion (240 ± 100 ng/100 mg; P < 0.001) or placenta (300 ± 130 ng/100 mg; P< 0.001). Three to 36 times more PP14 was released into culture medium by decidual explants compared with the other tissues, and cycloheximide decreased this release by 3

AbstractγδT cells represent the majority of lymphocytes in several mucosal tissues where they contribute to tissue homoeostasis, microbial defence and wound repair. Here we characterise a population of interleukin (IL) 17-producing γδ (γδ17) T cells that seed the testis of naive C57BL/6 mice, expand at puberty and persist throughout adulthood. We show that this population is foetal-derived and displays a T-cell receptor (TCR) repertoire highly biased towards Vγ6-containing rearrangements. These γδ17 cells were the major source of IL-17 in the testis, whereas αβ T cells mostly provided interfer

Abstract:

The mechanisms underlying detachment of foetal membranes after birth in cows are still unclear. To address this problem in a systematic manner, we performed the first holistic transcriptome study of bovine placentomes antepartum (AP;n=4 cows) and intrapartum (IP;n=4 cows) using Affymetrix GeneChip Bovine Genome Arrays. Three placentomes were extracted from each cow, and tissue samples from the contact zones of the placentomes (foeto-maternal units) were recovered by systematic random sampling and processed for RNA extraction and for stereological quantification of cellular composition.

Abstract:

Spontaneous preterm birth is the leading cause of neonatal mortality and morbidity globally. Activation of the maternal immune system leads to a downstream cascade of proinflammatory events that culminate in the activation of spontaneous uterine contractions and the rupture of the foetal membranes. Anti-inflammatory agents may be a novel therapeutic approach to prevent inflammation-induced myometrial contractions and premature rupture of foetal membranes. The polyphenol gallic acid has been previously shown to exert potent anti-inflammatory effects. Thus, this study aimed to determine the effe

Abstract:

In the ovine foetus brown adipose tissue (BAT) is mainly found in the perirenal region and grows rapidly relative to body weight between 70 to 120 days of gestation (Alexander, 1978). After this stage only a small amount of BAT growth occurs in comparison with that of the whole foetus, and in the case of undernutrition may decline (Alexander, 1978).

Background: The synchronised depolarization and repolarisation of the atria and ventricles is achieved by specialised cardiac cells that generate an electrical impulse and propagate it along the conducting system in the myocardial tissue, leading to rhythmic activity of the atria and ventricles. Abnormalities of these rhythms lead to foetal arrhythmia.Methods: A retrospective observational study was conducted in a tertiary care hospital over period of one year to study the course and perinatal outcome of women with foetal arrhythmias.Results: The confinement in the study period was N=4302, of

Without immunotherapy, this autoantibody mediated disorder comes with substantial mortality with a rate of 15-30%.

Abstract:

Many recent studies have used a temperature sensitive strain of the simian virus 40 large tumor antigen gene (tsA58) to immortalise foetal neural cells by gene insertion in vitro. The H-2Kb-tsA58 transgenic mouse circumvents the need for such genetic manipulation as the tsA58 gene is already within its genome. The results from this study show that foetal neural cells from this mouse do no proliferate and form tumors after grafting to adult brain; rather they survive and differentiate in a manner similar to nontransgenic foetal neural transplants. Therefore, this mouse is a potential source of

The data presented clearly suggest that relative amounts of mRNAs for elastins a, b and c are developmentally regulated in foetal-calf nuchal ligament and aorta and that this regulation is tissue-specific. In nuchal ligament, at earlier stages of foetal development, the relative amounts of mRNAs for elastins a and b are very low. After the foetal age of about 6 months the relative amount of mRNA for elastin b begins to increase. This is followed by an increase in the relative amount of mRNA for elastin a. In aorta, with increasing foetal age, the relative amounts of mRNAs for elastins b and c

Cellular proliferation of rat glioma C6 BU1 cells in tissue culture is dependent on the presence of either calf or foetal-calf serum in the medium. Foetal-calf serum stimulated a high-affinity GTPase in membranes derived from C6 BU1 cells. Pretreatment of the cells with pertussis toxin decreased the high-affinity GTPase activity substantially, and attenuated the foetal-calf-serum-stimulated increase in this GTPase activity. Cholera toxin, in contrast, did not modulate the response to foetal-calf serum. Foetal-calf serum did not inhibit adenylate cyclase activity in membranes of these cells, in
