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.

Methods of producing RPE cells

The present disclosure is related to methods for forming a stem cell bank. The methods include obtaining a first stem cell from a multi-cell fertilized embryo, expanding the first stem cell into two or more descendant stem cells, and storing at least one of the descendant stem cells to form the stem cell bank. Also disclosed is a kit that can be used for making the stem cell bank during in vitro fertilization. If desired, the HLA serotype of the stem cells can be determined prior to storage.
