It is essential to know the genetic stability of the hESC lines before progressing to clinical trials. In this study they evaluated the molecular karyotype of 25 clinical-grade hESC lines by whole-genome single nucleotide polymorphism (SNP) array analysis. The hESC lines were all cultured on laminin-521.

Here the authors describe production of hESC-RPE cells in a xeno-free and defined manner and present evidence of functional integration of clinically compliant hESC-RPE in a large-eyed disease model. Human recombinant laminin-521 effectively supports differentiation of clinically compliant hESC-RPE that are effeiciently used in a minimally invasive surgical procedure for high-yield functional long-term hESC-RPE integration with photoreceptor preservation. These findings have important implications for ongoing and future clinical studies for the development of a safe and efficient cell replacement therapy for geographic atrophy.
