Targeting Notum Improves Tissue Regeneration

Posted by in categories: biotech/medical, life extension

Researchers at the University of Helsinki have shown why the regenerative capacity of the cells lining the intestines declines with age and that targeting a particular enzyme can restore the regenerative potential of this tissue.

Notum blocks the Wnt pathway

During normal function, the cells of the intestinal epithelium, a single cell layer that forms the lining of both the small and large intestine, are replaced by stem cells, which create healthy replacement cells to counter losses from injury, damage, disease, and aging. These cells are roused into action via the Wnt signaling pathway, which is activated through signals sent by other cells in the tissue.
