TLDR Hedgehog signaling is crucial for mammary gland development over hair follicles.
The document reviewed the roles of Hedgehog (Hh) and Gli proteins in the development of murine embryonic mammary glands, focusing on the Extratoes mutation, a functional null-mutation of the Gli3 gene. It proposed that the off-state of Hh signaling, mediated by the Gli3-repressor, was crucial for determining mammary gland fate over hair follicle fate in the trunk surface ectoderm.

January 2005 in “BioEssays” Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.
The document concludes that the development of certain tumors is influenced by genetic background and that a specific gene modification can lead to tumor regression and reduced growth.
