Heparan sulfate negatively regulates intestinal stem cell proliferation in Drosophila adult midgut
Tissue homeostasis is maintained by differentiated progeny of residential stem cells.Both extrinsic signals and intrinsic factors play critical roles in the Jandy TruFit Bubbler Parts proliferation and differentiation of adult intestinal stem cells (ISCs).However, how extrinsic signals are transduced into ISCs still remains unclear.Here, we find th
