Fig. 6From: Modulation of Wnt/BMP pathways during corneal differentiation of hPSC maintains ABCG2-positive LSC population that demonstrates increased regenerative potentialProposed differentiation hierarchy of the LSC populations in the human cornea. a Schematic illustration of the human limbus, proposing that populations of both quiescent (purple) and actively cycling (green) LSCs coexist in the limbal crypts, from where their TAC (blue) progeny migrate towards the central cornea, going through several cell divisions before terminal differentiation into mature (white) CECs. b Representation of the interplay between separate limbal cell populations, identified by distinct marker expression profiles.
