Full textBecause of the worldwide shortage of graftable corneas used to treat corneal pathlogies, alternatives to restore visual impairments, such as the production of a human cornea tissues by tissue engineering, have been considered. To treat injuries affecting the corneal epithelium, such as limbal stem cell deficiency (LSCD), the corneal equivalent must have an epithelium able to self-renewal allowing healing of the patient's corneal epithelium after the transplantation. To culture human corneal epithelial cells (HCECs) in vitro, the use of a feeder layer is necessary so as to maintain the subpopulation of corneal stem cells, which is essential for the proper proliferation of these cells. Therefore, the culture conditions must allow the maintenance of the stem phenotype of these cells, while promoting their proliferation and delaying their terminal differentiation. Other parameters, such as the post-mortem interval of the corneal tissue from which the cultured HCECs are derived, can influence the success of the culture. It is therefore important to characterize the cultures of HCECs in order to optimize the success of a transplant, namely, when these cells are transplanted in order to regenerate the injured corneal epithelium of a patient. The work presented in this thesis demonstrates that the co-culture of HCECs with a murine feeder layer resulted in a significant increase in the expression and the binding to DNA of NFI. This was shown to be caused by strong expression of the NFI-B isoform with increased stability due to hyper-glycosylation. The preservation of the NFI-B isoform with cellular passages was correlated with a faster differentiation of the HCECs in culture. This work also shows that the effect of this murine feeder layer on the expression levels and the DNA binding capacity of the transcription factors Sp1 and NFI was confirmed in another cell type. Indeed, the co-culture of human corneal endothelial cells with the murine feeder layer also caused a significant increase in the expression and binding to DNA of NFI. In this study, this was associated with an improvement in the morphology of human corneal endothelial cells. This work also showed that post-mortem interval could have a negative influence on the proliferation of HCECs and on the maintenance of stem cells during monolayer cultures. When the same cell populations were used to reconstruct a human cornea with tissue engineering, the healing capacity of the reconstructed corneal epithelia was decreased by the increase in post-mortem interval. This was notably validated by a study of the transcriptome of these cell populations by DNA microarray. It has also been shown that a graft reconstructed with HCECs co-cultivated with human feeder layer has enabled to heal the corneal surface an eye with LSCD. These different results highlight that the use of a human feeder layer for culture, associated with a short post-mortem interval of the donor tissues, is to be favoured in order to promote a good in vitro proliferation of HCECs cultivated in monolayer.

Full textBackground: Human corneal endothelial cells (HCEC) easily become fibroblastic when cultured, rendering them unsuitable for tissue engineering of the cornea. Transforming growth factor β (TGF-β) could be a key factor in this phenomenon; however, it is also known to maintain the endothelium in a quiescent state in vivo. Purpose: To compare the effects of TGF-β1 on HCEC’s phenotype during either the proliferation or the maturation phase of the cultures and optimize culture conditions for HCECs. Morphology, functionality markers, trans-endothelial resistance and permeability of the cultures were analyzed at confluency (proliferation phase) and after the post-confluence maturation phase. Results: Adding TGF-β1 during proliferation produced fibroblastic HCECs and loss of the cell junction’s markers, independently from the presence of EGF. On contrast, during the maturation phase, HCECs had an endothelial phenotype and functional cell junctions. They produced a high trans-endothelial resistance and a low permeability. Overall, results show that TGF-β1 promotes formation of a typical leaky endothelial barrier during the maturation phase of cultured HCECs, thus approaching the physiological properties of in vivo HCECs.

Full textBackground: Cultured human corneal endothelial cells (HCEC) often adopt a fibroblastic-like morphology [endothelial-mesenchymal transition (EMT)], making them unusable in tissue engineering due to the associated loss of function. Purpose: In agreement with previous work from our laboratory and scientific literature, we separately investigated the effects of culture under physiological hydrostatic pressure (18 mmHg) and the antagonism of EMT on HCEC functionality. Methods: First, seeding HCEC on decellularized corneal stromas and culture in an artificial anterior chamber allowed to submit HCEC to hydrostatic pressure. Second, the following putative EMT antagonists agents were studied: SB431542, dexamethasone and BMP-7. Results: Physiological hydrostatic pressure and EMT antagonism by SB431542 and dexamethasone are effective ways to maintain and improve HCEC functionality in vitro.
