Sox9 Is Essential for Outer Root Sheath Differentiation and the Formation of the Hair Stem Cell Compartment
BACKGROUND The mammalian hair represents an unparalleled model system to understand both developmental processes and stem cell biology. The hair follicle consists of several concentric epithelial sheaths with the outer root sheath (ORS) forming the outermost layer. Functionally, the ORS has been implicated in the migration of hair stem cells from the stem cell niche toward the hair bulb. Howeve...

متن کاملSox9 Increases the Proliferation and Colony-forming Activity of Outer Root Sheath Cells Cultured In Vitro.
BACKGROUND β-catenin plays a pivotal role in hair follicle development and hair growth cycle. OBJECTIVE The aim of this study was to identify β-catenin-regulated genes in cultured human hair outer root sheath (ORS) cells. METHODS Primary cultured ORS cells were transduced with recombinant adenovirus expressing N-terminal truncated β-catenin (constitutive active form), and β-catenin-regulate...
متن کاملManipulation of outer root sheath cell survival perturbs the hair-growth cycle.
Transgenic mice that overexpress the anti-apoptotic gene bcl-xL under the control of the keratin 14 promoter have significantly shorter hair than non-transgenic littermates. The deficit in hair length correlated with a decrease in the duration of anagen, the growth phase of the hair cycle. A prolongation in telogen, the resting phase of the hair cycle, was also observed in adult animals. In the...
