Micrographs of cells at different stages during the induction of hiPSCs to neural progenitor cells (NPCs)
(A) Typical morphology of hiPSCs cultured in induction medium at 7 days.
(B) Embryoid body (EB) formed in resuspension growth medium.
(C) Neurosphere (NSP) in NSP medium.
(D) Neural Progenitor cells cultured in NPC medium.
(E) Some aggregates (white dot) could be noticed in NPC cultures. Scale bars, 100 μm.
