The mammary gland cell growth and differentiation are under the control of both systemic hormones and locally produced growth factors. Among all these important hormones and growth factors, estrogen plays a central role in mammary gland development. The biological function of estrogen is mediated by estrogen receptor α (ERα) and estrogen receptor β (ERβ). Both ERα and ERβ are expressed in the mammary gland, but with distinct expression patterns. In the mammary gland, ERα has been proved to be the estrogen receptor that mediates the mitogenic function of estrogen. However the function of ERβ in mammary cell proliferation is less ...
