Methods for differentiating cells

Abstract

A method for producing eyefield progenitor cells, including: (a) obtaining a starting population comprising human pluripotent stem cells (hPSCs) that are dissociated to essentially single cells; (b) culturing said hPSCs to a contact-inhibited monolayer; (c) contacting said hPSC monolayer in a primary differentiation medium to generate a homogeneous, contact-inhibited monolayer of anterior neuroectodermal cells (ANECs); (d) dissociating said homogeneous ANECs from (c) into essentially single cells; (e) forming dissociated ANECs into size-controlled and homogeneous 3D aggregates (ANEBs), wherein the ANEBs are 3D aggregates of anterior neuroectodermal cells that are distinct from embryoid bodies; and (f) culturing said ANEBs in a primary differentiation medium in suspension to further differentiate them to Eyefield Progenitor Cells (EFPCs).
