The self‐renewal and differentiation of tissue stem cells must be tightly controlled. Unrestrained self‐renewal leads to over‐proliferation of stem cells, which may cause tumor formation, while uncontrolled differentiation leads to depletion of the stem cell pool. In this issue of The EMBO Journal , Demitrack et al (2015) show that the Notch pathway is a key regulator of Lgr5 antral stem cell self‐renewal and differentiation. Notch signaling controls the proliferation and differentiation of stem cells as well as gastric tissue growth, while uncontrolled Notch activity in stem cells leads to polyp formation.
