摘要

Limbal epithelial stem cells (LESC's) are responsible for corneal epithelium regeneration due to corneal damage, or LESC deficiency. One of the major challenges of LESC's culture is their optimal derivation and expansion in a chemically defined culture media; with the purpose to generate enough amounts of cells with the correct genotype and phenotype. Chemically defined conditions would avoid cells that could compromise the security and efficiency of cell therapy. The need for alternative options to cadaveric corneas will continue to grow in importance as a result of increasing incidence of keratoplasties, hence if we investigate the use of different proteins as extracellular matrix (Laminin, Fibronectin, Collagen type I and Collagen Type IV) during the expansion of LESC's, we could optimize a "selective expansion of LESC's".
