Abstract Lichen planopilaris (LPP) is a difficult to treat condition leading to permanent hair loss and scarring. Pathobiologically, LPP shows T- cell mediated interferon-γ driven loss of keratin 15 (K15) positive hair follicle (HF) epithelial stem cells (eHFSCs) due to immune privilege (IP) collapse and pathological epithelial-mesenchymal transition (EMT). This exhausts the eHFSC pool; impacting the HF's capacity to regenerate and cycle and ultimately resulting in HF destruction, fibrosis and scarring. PMID: 32471007 [PubMed - as supplied by publisher]

Both hair graying and hair loss with age are well researched topics, but there remains considerable uncertainty over which of the possible mechanisms involved are the most relevant, or most useful as targets for therapy. This state of affairs is well illustrated by the feverish interest that attends any possible advance towards reversing male and female pattern baldness. Also the sizable marketplaces devoted to treatments that work poorly, if at all. Today's trial results are interesting, in that I don't recall seeing stem cell factors being used topically before. There is of course a great deal of nonsense and unsc...

Abstract Alopecia is resulted from various factors that can decrease the regeneration capability of hair follicles and affect hair cycles. This process can be devastating physically and psychologically. Nevertheless, the available treatment strategies are limited, and the therapeutic outcomes are not satisfactory. According to the possible pathogenesis of nonscarring alopecia, especially androgenetic alopecia, recovering or replenishing the signals responsible for hair follicle stem cells activation is a promising strategy for hair regeneration. Recently, stem cell-based therapies, especially those based on the st...

Abstract The pilosebaceous unit is the triad comprising of hair follicle, arrector pilli muscle, and sebaceous gland. Drug delivery to and through the hair follicles has garnered much attention of the researchers and the hair follicles represent an attractive target site via topical applications. They are bordered by capillaries and antigen-presenting cells, connected to the sebaceous glands and the bulge region of the hair follicle anchors the stem cells. The nano lipid carriers have the propensity to penetrate through the skin via transcellular route, intracellular route and follicular route. It has been establi...

Abstract Skin aging is accompanied by hair loss due to impairments in hair follicle (HF) epithelial progenitor cells and their mesenchymal niche. This inductive mesenchyme, called dermal papilla (DP), undergoes progressive cell loss and eventual miniaturization that contributes to HF pathogenesis. Using laser ablation and fate mapping, we show that HF dermal stem cells (hfDSCs) reconstitute the damaged DP and maintain hair growth, suggesting that hfDSC dysfunction may trigger degeneration of the inductive niche. Fate mapping over 24 months revealed progressive hfDSC depletion, and in vivo clonal ana...

AbstractPurposeCranial irradiation results in cognitive decline, which is hypothesized to be partially attributable to hippocampal injury and stem cell loss. Recent advances allow for targeted reduction of radiation dose to the hippocampi while maintaining adequate dose coverage to the brain parenchyma and additional increasing dose to brain metastases, a approach called hippocampal avoidance whole brain radiation therapy with a simultaneous integrated boost (HA-WBRT  + SIB.) We review our early clinical experience with HA-WBRT + SIB.Materials and methodsWe evaluated treatments and clinical outc...

Hair follicles undergo recurrent growth, regression, and resting phases throughout postnatal life, which is supported by hair follicle stem cells (HFSCs). The niche components of HFSCs are important to maintain their quiescence and stemness. Gasdermin A3 (Gsdma3) gain-of-function mutations in mice cause chronic skin inflammation, aberrant hair cycle, and progressive hair loss, reminiscent of scarring alopecia in humans. However, the mechanism underlying these defects remains elusive. Here, we used a combined Cre/loxP and rtTA/TRE system to study the spatiotemporal effect of Gsdma3 overexpression on distinct hair cycle stages.

Contributors : Hanseul Yang ; Rene Adam ; Elaine FuchsSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusTissue homeostasis and regeneration rely upon resident stem cells (SCs), whose behavior is regulated through niche-dependent crosstalk. The mechanisms underlying SC maintenance are still unfolding. Here, using hair follicles (HFs) as model and spatiotemporal gene ablation in mice, we uncover transcription factors (TFs) NFIB and NFIX as guardians of the process. Complete NFI ablation causes SC depletion and hair loss which resembles irreversible alopecia in humans, who in...
