The disclosure pertains to a defined cell culture medium for the expansion of human retinal progenitors, comprising or consisting of a nutrient medium, a SHH-pathway activator and a GSK3 inhibitor. To the use of the defined cell culture medium for the expansion of retinal progenitors, as well as to an in vitro method for expanding retinal progenitors, comprising: (i) placing a culture of human retinal progenitors in a defined cell culture medium as defined in claimsto; and (ii) culturing the cells in said defined cell culture medium.

Compositions and methods for efficient amplification of retinal progenitors cells

A method for in vitro obtaining human retinal progenitors, includes the steps of (i) placing an adherent culture of human pluripotent stem cells in a pro-neural medium; and (ii) maintaining this culture in the pro-neural medium until the appearance of pigmented cells and/or of neuroepithelial-like structures. Additional steps can be performed to obtain RPE cells and/or precursors of the neural retina.
