human_reference_atlas part of has characterizing marker set has marker component KRT20 cell cell type (from CL) transit amplifying cell of colon A rapidly proliferating population of cells that differentiate from stem cells of the intestinal crypt of the colon. Stem cells located in the crypts of Lieberkühn give rise to proliferating progenitor or transit amplifying cells that differentiate into the four major epithelial cell types. These include columnar absorptive cells or enterocytes, mucous secreting goblet cells, enteroendocrine cells and paneth cells. transient amplifying cell colon transit amplifying cell transient amplifying cell of crypt of Lieberkuhn of colon transit-amplifying cell of colon CT transient amplifying cell transit amplifying cell of crypt of Lieberkuhn of colon transient amplifying cell of colon CL:0009011 transit amplifying cell of large intestine Homo sapiens sequence collection large intestine anal canal cecum mucosa colonic mucosa ileocecal valve rectum caecum vermiform appendix ascending colon transverse colon descending colon sigmoid colon mucosa of anal canal mucosa of appendix epithelium of crypt of Lieberkuhn crypt of Lieberkuhn of colon splenic flexure of colon hepatic flexure of colon epithelium of crypt of Lieberkuhn of large intestine
