Full textOBJECTIVE: Common problems affecting patients with tracheal replacement are infections and stenosis caused by granulation tissue. These complications can be minimized by establishing a differentiated respiratory epithelium, which facilitates mucocilliary clearance. The basal cells are regarded as the progenitor cells of the human respiratory epithelium (HRE). They are known to divide and possess the ability to differentiate. These cells can be enriched by means of magnetic cell sorting (MACS) for the purpose of cultivation. METHODS: The inferior nasal turbinates of 80 patients (mean age 40 ± 14 years) are used as cell source. The HRE-cells are isolated by a standard preparation using an enzymatic digestion with Dispase II (2,4 U/ml). The HRE-cells are plated on culture dishes coated with Collagen A in serum-free AECG-Medium. Several extracellular cell markers including GSA I B4, CD44S and CD44v6 are tested by immunohistochemistry. Only CD44v6 shows specific staining of basal cells. The progenitor cells of mixed single cell suspensions of HRE-cells are marked with monoclonal antibodies against CD44v6 and are conjugated with Goat-Anti-Mouse-Microbeads. Enrichment of progenitor cells is achieved by MACS using a positive selection protocol. RESULTS: The preparation of the nasal turbinates yields viable single cell suspensions of HRE-cells (viability > 80%, n = 30). Adhesion of HRE-cells is enhanced significantly (p < 0,0145, n = 5) by coating the culture dishes with Collagen A. The kinetics of proliferation of HRE-cell-cultures can be characterized by the population doubling time (tPD = 23 ± 3h, n = 3). In the course of one month the capacity of proliferation is approximated by cell expansion (383fold, n = 6). Magnetic cell sorting results in a cell fraction (20 ± 2%, n = 5) positive for CD44v6. The separated cells are cultured on Collagen A for one week, where they all show adequate proliferation. CONCLUSIONS: The results indicate that CD44v6 is a specific marker for basal cells and enables the enrichment of a positive cell fraction via application of MACS. Further studies will be required to investigate the potential of such a magnetically separated population of basal cells to generate a differentiated respiratory epithelium on a tracheal prosthesis.

Full textThe replacement of extensive tracheal defects resulting from intensive care medicine, trauma, or large resections is still challenged by the re-epithelialization of an autologous or alloplastic trachea replacement. Therefore, this thesis was performed to investigate the potential of culture expanded human respiratory epithelial cells (hREC) to regenerate a functional epithelium for trachea tissue engineering.hREC from nasal turbinates were freshly isolated, expanded and subsequently cultured in high-density multilayers to allow epithelial differentiation. Composition of epithelial cells in native respiratory epithelial tissue and culture expanded hREC were analyzed by histological staining and by immunohistochemical staining with the specific antibodies. Differentiation of culture expanded hREC was further characterized by gene expression analysis of a cytokeratin pattern using semi-quantitative real-time RT-PCR technique. Furthermore, basal cells known as progenitors of the respiratory epithelium were seperated by Fluorescense Activated Cell Sorting with the basal cell specific antibodies CD49f and CD104. Co-cultures of hREC and human chondrocytes (hCHO) or human cartilage respectively were compared to Air-Liquid-Interface cultures containing hREC and hCHO.Histological and immunohistochemical staining and Scanning Electron Microscopy pictures of hREC in differentiation cultures demonstrated basal cells covering the collagenous matrix. These cells formed a cellular multilayer, which is composed of a basal layer of undifferentiated basal cells and an upper layer of cells differentiating along the squamous metaplasia and ciliated cell lineage. Lineage development of cultured hREC was further documented by the induction of specific cytokeratins. Our results suggest that culture expanded hREC have the potential to colonize collagen coated biomaterials as well as autologous cartilage grafts and to regenerate epithelial cell types for trachea tissue engineering.

Full textThis thesis focused on the objective to investigate the neuroendocrine cells in the respiratory tracts of mice which connect to sensory nervous fibers. In the preceding trials it was possible to determine the amount of the released CGRP after the stimulation with bitter substances. The method of measuring the release of CGRP from a variety of organs was established by Prof. Reeh and his working group. The aim of this work was to investigate where the released CGRP originates from and if the stimulation of brush cells with bitter substances leads to the release of CGRP in the neuroendocrine cells. Based on the electron-microscopic analysis and the three dimensional reconstruction, a correlation between the neuroendocrine cells in the epithelium of mice trachea and the sensory nervous fibers was observed. The immunhistochemical examinations displayed that the stimulation with Denatonium most probably leads to the release of CGRP through intraepithelial fibers. This presumption is reflected in the changed morphology as well as the lower quantity of intraepithelial fibers after the stimulation with Denatonium. Furthermore, the presumption is supported by the fact that neither the number of neuroendocrine cells, nor the appearance and number of extraepithelial fibers led to a change after denationium stimulation. With regards to the executed trials with TRPM5 gene-deficient mice it was observed that the stimulation with Denatonium does not impact the number of neuroendocrine cells. This again supports the finding of the previous trials which showed that CGRP was not released by neuroendocrine cells. Moreover, it can be concluded from this result that the release of CGRP is independent from the existence of brush cells. Overall the trials showed that the release of CGRP through intraepithelial fibers was triggered by the stimulation with bitter substances. Based on these results it would be interesting to investigate the effects of the release and to understand the role of substance P in this correlation

Full textIn this work, a vascularized implant for the treatment for tracheal defects was developed according to GMP standards. For this purpose, a part of porcine small intestine was prepared, decellularized and sterilized. The remaining matrix, trademarked BioVaSc “Biological, Vascularized Scaffold”, was colonized with isolated and cultured cells from the patient and then matured for two weeks in a bioreactor system. Finally, the prepared for implantation autologous implant was extensively characterized. After the integrity check of the vessel system the decellularization process was started, which is performed by removing the porcine cells with sodium desoxycholat and enzymatic degradation of the residual DNA. As traces of sodium desoxycholat could negatively affect the seeding of the autologous cells, a test was established to demonstrate the depletion of sodium desoxycholat to acceptable traces in the final matrix preparation. Furthermore, the porcine starting material for the BioVaSc contains endotoxins, which could trigger immune reactions in the recipient if not efficiently removed. The legal limit for endotoxine levels in pharmaceutical products could be achieved through modifications of the protocol. In order to establish a GMP compliant process, specially certified chemicals were used wherever possible. The protocol was optimized until histological analysis showed only few residual cells and DNA residues. The quantitative DNA analysis revealed a decrease of 97 % of the initial DNA content. To determine storage stability, a tensile test to check elasticity of the BioVaSc was established. To colonize the matrix, autologous microvascular endothelial cells, fibroblasts and skeletal muscle cells were used. The protocols were established and optimized under GMP conditions and, wherever possible, certified reagents were used. For accurate characterization of these cells, immunohistology analyses were performed at each of the four passages for all cell types. For the final manufacturing of the autologous implant, microvascular endothelial cells were introduced into the vascular system of the BioVaSc and were cultured for seven days in a custom made bioreactor system under defined shear stress conditions resembling the human blood pressure. This was followed by culturing of skeletal muscle cells and fibroblasts in the lumen of the gut, followed by an additional seven-day culture period. Colonization of the vascular system had to be optimized in order to increase the population density as well as the efficiency of reseeding. The lumen was fully populated with fibroblasts and skeletal muscle cells by the established protocol. However, the discrimination between fibroblasts and skeletal muscle cells with normal histology was difficult because no fitting antibody was available. After a two-week culture in the custom made bioreactor system the analysis showed vital cells in the vascular structures and in the lumen of the BioVaSc. Further histological analysis were performed. In order to explore alternative cell sources, the BioVaSc was reseeded with upcyte mvEC. These transfected cells are highly proliferative and show typical endothelial markers. After fourteen days of culture in the bioreactor system, cells could be detected in vascular structures, lumen and in connective tissue. Live / dead staining and MTT identified vital cells within vascular structures. The histological analysis revealed expression of CD31, eNOS and vWF. Furthermore, the matrix was reseeded with mesenchymal stem cells; to test if shear stress triggers differentiation into endothelial like cells. This was checked through displaying the corresponding endothelial markers in histological analyses. After fourteen days of culture in the bioreactor system, histological analyzes show no expression of CD31 or vWF factor. Vital cells could be detected
