This study identified specific germline and somatic mutations in the Phospholipase C Delta 1 gene as high-risk factors for developing hereditary trichilemmal cysts, involving a monoallelic two-hit mechanism.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study found distinct gene expression patterns in the blood of alopecia areata patients, suggesting involvement of immune processes and new pathways like Wnt signaling and apoptosis in disease pathogenesis.

This study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This study found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

This study found that lncRNA-000133 may play a role in secondary hair follicle reconstruction and cashmere fiber growth in goats, potentially through its interaction with the methylation of its regulatory region and dermal papilla cells.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This letter discusses how outdated measurement technology may obscure evidence of essential fatty acid deficiency in low-fat diet patients, potentially leading to undiagnosed EFA insufficiencies related to heart disease.

This review discusses the cosmetic potential of Southeast Asian herbs and highlights the need for more systematic scientific evaluation of their efficacy and safety.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This review discusses the mechanism and side effects of smoothened inhibitors for advanced basal cell carcinoma, reporting no new clinical results and highlighting current management strategies for these adverse events.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This review discusses how vitamin D and calcium signaling are essential for wound healing by activating epidermal and hair follicle stem cells, noting that deficiencies may lead to delayed or chronic wounds.

In this study, EGCG from green tea promoted mink hair follicle growth and cell proliferation at specific concentrations, potentially through activation of Shh and AKT signaling pathways.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study reported that pathways related to apoptosis, cell proliferation, and WNT signaling might be key drivers of hair loss in androgenetic alopecia, guiding potential targets for therapy development.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study demonstrated that a new non-invasive method for collecting and analyzing mouse hair follicles could replace traditional biopsy methods, providing advantages for translational research and routine applications.

This study found that exogenous glutamic acid can promote hair growth and keratinocyte proliferation, suggesting a novel signalling pathway in the skin.
