Crypt Definition & Meaning - Merriam-Webster

WebObjective: The crypt population in the human intestine is dynamic: crypts can divide to produce two new daughter crypts through a process termed crypt fission, but whether this is balanced by a second process to remove crypts, as recently shown in mouse models, is uncertain. We examined whether crypt fusion (the process of two neighbouring crypts … WebThe crypt is a contiguous pocket of epithelial cells at the base of the villus, in which intestinal stem cells (ISCs) are periodically activated to produce progenitor or transit amplifying (TA) cells which are committed to produce mature cell lineages [43,44,45].
