Epithelial architecture. a The lineages produced by GsSCs are composed of CCs, ICs and EEs. The LFCs and FCs are present in the posterior CCR. A: anterior, P: posterior. b The MG consists of two types of mature cells, with ISCs that are evenly distributed. c The HPZ is where damage-induced self-renewal is maintained by HSCs. Slow-cycling mode (ASCZ and PSCZ) is maintained by the HSCs in ASCZ. The TA cells in RCZ are involved in the differentiation of DCZ
