DERIVATION OF HUMAN EMBRYONIC STEM CELL LINES FROM POOR QUALITY EMBRYOS

embryogenesis serves to provide guidelines for carrying out in vitro differentiation of hESCs, major challenges still remain. The biggest of these challenges is perhaps the heterogeneity in lineages of differentiated cells obtained through most in vitro protocols. This is primar[r]
