Abstract

Pregnancy induces a rapid and controlled expansion of mammary stem cells. In this issue of Developmental Cell, Desgrosellier et al. (2014) show that β3-integrin is required downstream of hormonal signaling and TGFβ2 to regulate mammary stem cell number and alveolar development specifically during early pregnancy.
