WebMay 20, 2024 · Transit amplifying (TA) cells reside in the zone directly above the stem cell zone and are common progenitors of the absorptive lineage. TAs replicate up to six times with an even shorter cell cycle (∼12 h) than CBC cells before they enter a postmitotic state and differentiate further ( Potten, 1998 ). WebThe intestinal epithelium constitutes a dynamic physical barrier segregating the luminal content from the underlying mucosal tissue. Following injury, the epithelial integrity is restored by rapid migration of intestinal epithelial cells (IECs) across the denuded area in a process known as wound healing.
