Crypt ablation
WebMar 5, 2024 · After ISC ablation, ectopic Ascl2 expression in colonic crypts allowed us to detect and purify actively dedifferentiating cells. mRNA profiles of restorative populations and single cells lacked evidence for a favored +4 cell source and revealed dynamic transcriptional flux in colonocytes and goblet cells, each converging toward ISCs. WebPan-epithelial deletion of SMARCA4 in the small intestine resulted in crypt ablation, while partial deficiency of SMARCA4 led to gradual repopulation of wild-type cells in the intestinal mucosa. On the other hand, SMARCA4 deficiency in the large intestinal epithelium was compensated by upregulation of SMARCA2.
