WebApr 5, 2024 · Moreover, small intestinal crypts have a high fission rate to support the growth of small intestines in infants and young animals [43–45]. Given that small epithelial regeneration and crypt fission are driven by ISCs [ 23 , 46 ], we tested whether early weaning affects the activity of ISCs to drive epithelial regeneration and crypt fission. WebCrypt cells actively secrete electrolytes, leading to water secretion: The apical or lumenal membrane of crypt epithelial cells contain a ion channel of immense medical significance - a cyclic AMP-dependent chloride channel …
