Spatial and Temporal Regulation of Hair Follicle Progenitors by Hedgehog Signalling
نویسنده
چکیده
Epithelial organs such as the vertebrate hair undergo programmed self-renewal in part by controlling the growth of progenitor cells. The hedgehog signaling pathway regulates progenitor growth in a variety of tissues. This chapter discusses evidence for how the skin regulates the production of Shh ligand, the reception of the Shh signal, and maintenance of the signal to promote hair morphogenesis and prevent tumor formation.

Indian hedgehog and beta-catenin signaling: role in the sebaceous lineage of normal and neoplastic mammalian epidermis.
In mammalian epidermis, the level of beta-catenin signaling regulates lineage selection by stem cell progeny. High levels of beta-catenin stimulate formation of hair follicles, whereas low levels favor differentiation into interfollicular epidermis and sebocytes. In transgenic mouse epidermis, overexpression of beta-catenin leads to formation of hair follicle tumors, whereas overexpression of N...
متن کاملMolecular pathways involved in hair follicle tumor formation: all about mammalian target of rapamycin?
Hair follicle tumors show a broad range of phenotypic variability and diverse histopathological characteristics. To date, different genes and signalling cascades have been implicated in the development and growth of these tumors including the sonic hedgehog, nuclear factor kappa-B and wingless pathway. While the former three have received ample attention, little is known about the possible role...
متن کاملKrox20, a novel candidate for the regulatory hierarchy that controls hair shaft bending
Murine hair follicle morphogenesis gives rise to four distinct pelage follicle types that produce hair shafts differing in length, the number of medulla columns, and the presence and number of bends. Recently, Igfbp5 was identified as the first molecular marker that distinguishes among different hair follicle types and shown to mark zigzag hairs. Further, it was demonstrated that Igfbp5 express...
متن کاملAn in vivo comparative study of sonic, desert and Indian hedgehog reveals that hedgehog pathway activity regulates epidermal stem cell homeostasis.
Despite the well-characterised role of sonic hedgehog (Shh) in promoting interfollicular basal cell proliferation and hair follicle downgrowth, the role of hedgehog signalling during epidermal stem cell fate remains largely uncharacterised. In order to determine whether the three vertebrate hedgehog molecules play a role in regulating epidermal renewal we overexpressed sonic (Shh), desert (Dhh)...
متن کاملBasal cell carcinoma preferentially arises from stem cells within hair follicle and mechanosensory niches.
Basal cell carcinoma (BCC) is characterized by frequent loss of PTCH1, leading to constitutive activation of the Hedgehog pathway. Although the requirement for Hedgehog in BCC is well established, the identity of disease-initiating cells and the compartments in which they reside remain controversial. By using several inducible Cre drivers to delete Ptch1 in different cell compartments in mice, ...
