Crypts in biology
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]. What are crypts responsible for? WebFeb 26, 2024 · This hypothesis has been supported by immunohistochemistry, qRT-PCR analysis, and ChIP-sequencing demonstrating that FOXA1/2 co-expresses in cells that express high levels of SOX9 within the intestinal crypt. These studies provide further understanding of how stem cell identity is normally regulated in the cells of the intestinal …
