Abstract
The present disclosure relates to the use of laminin-521 in obtaining retinal pigment epithelium (RPE) cells. Pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in totally defined and xeno-free conditions. A first cell culture medium contains a growth factor, and a second cell culture medium does not contain growth factor. The stem cells are first exposed to the first cell culture medium, then exposed to the second cell culture medium for a longer time period. After a number of weeks, clinical grade RPE cells are obtained from the stem cells.
