Inhibition of β-catenin signalling in dermal fibroblasts enhances hair follicle regeneration during wound healing
New hair follicles (HFs) do not form in adult mammalian skin unless epidermal Wnt signalling is activated genetically or within large wounds. To understand the postnatal loss of hair forming ability we monitored HF formation at small circular (2 mm) wound sites. At P2, new HFs formed in back skin, but HF formation was markedly decreased by P21. Neonatal tail also formed wound-associated HFs, al...
متن کاملBaicalin increases hair follicle development by increasing canonical Wnt/β-catenin signaling and activating dermal papillar cells in mice
Baicalin is a traditional Chinese herbal medicine commonly used for hair loss, the precise molecular mechanism of which is unknown. In the present study, the mechanism of baicalin was investigated via the topical application of baicalin to reconstituted hair follicles on mice dorsa and evaluating the effect on canonical Wnt/β‑catenin signaling in the hair follicles and the activity of dermal pa...
متن کاملBeta-catenin activity in the dermal papilla of the hair follicle regulates pigment-type switching.
The switch between black and yellow pigment is mediated by the interaction between Melanocortin receptor 1 (Mc1r) and its antagonist Agouti, but the genetic and developmental mechanisms that modify this interaction to obtain different coat color in distinct environments are poorly understood. Here, the role of Wnt/β-catenin signaling in the regulation of pigment-type switching was studied. Loss...
متن کاملWnt5a Suppresses β-catenin Signaling during Hair Follicle Regeneration
Hair follicles display periodic growth. Wnt signaling is a critical regulator for hair follicle regeneration. Previously, we reported that Wnt5a inhibits the telogen-to-anagen transition of hair follicles, but the mechanism by which this process occurs has not yet been reported. Here, we determined the expression patterns of Wnt signaling pathway molecules by quantitative reverse transcription ...
متن کاملDissociated human dermal papilla cells induce hair follicle neogenesis in grafted dermal-epidermal composites
Cells. Human dermal papilla cells isolated from temporal scalp dermis (Promocell, Heidelberg, Germany) from five female donors (HDP41, HDP43, HDP44, HDP47, and HDP52) and one male donor (HDP60), named according to donor age in years, were propagated in vitro according to manufacturer’s recommendations. Keratinocytes were isolated from neonatal foreskins and were cultured in serum-free medium (K...
