This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

This study found that prolonged inhibition of DGAT1 in mice and dogs led to atrophy of sebaceous glands, with mice also experiencing alopecia, suggesting potential skin-related risks for humans using DGAT1 inhibitors.

Platelet-rich plasma therapy helps improve atrophic acne scars.

The document concludes that individualized treatment for malignant epithelial tumors is necessary and more research on metastatic squamous cell carcinoma treatments is needed.

This meta-analysis found that autologous cell-based therapies, especially stromal vascular fraction, significantly improved atrophic acne scars over control treatments, enhancing both clinical and patient-reported outcomes.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This study suggests that stress-induced premature senescence of dermal papilla cells may contribute to hair follicle aging by impairing critical epithelial-mesenchymal interactions and promoting inflammatory cytokine production.

This study identified genetic mutations linked to congenital ichthyosis in families from the UAE and Turkey, revealing a connection between keratinization disorders and impaired filaggrin processing.

This study found that topically delivering KGF-1 DNA plasmid increased epithelial thickness and skin strength, suggesting potential benefits for strengthening compromised skin.

This case report describes a 26-year-old female with linear morphea and unique alopecia characterized by atrophic follicular remnants, resembling telogen follicles but indicating permanent alopecia, unlike typical findings in morphea-related alopecia.

This study found that lichen planopilaris was the most common variant of cicatricial alopecia among patients, with perifollicular fibrosis being a prevalent histopathological feature.

This review discusses the potential pathogenic mechanisms of cicatricial alopecia and emphasizes the need for further research on treatment methods, but it reports no new clinical findings.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This study found that Wnt1/βcatenin signaling plays a crucial role in activating the epicardium and cardiac fibroblasts, which supports cardiac repair following acute ischemic injury.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This study suggests that intermediate-size hyaluronate fragments may enhance keratinocyte proliferation and improve skin thickness in atrophic conditions through a CD44-dependent mechanism.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This review discusses the role of the mineralocorticoid receptor in skin biology, highlighting its potential involvement in keratinocyte and hair physiology, and proposes it may affect the side effects of glucocorticoid use.

This review highlights that frontal fibrosing alopecia’s increasing incidence may involve immune, genetic, hormonal, and environmental factors, yet its pathogenesis remains complex and not fully understood.

This report is the first to associate Cronkhite-Canada syndrome with multiple myeloma, describing regenerative pseudopolyps in a 58-year-old woman rather than true adenomatous polyps.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This study found that high-dose radiation can induce accelerated cellular senescence, inflammation, and loss of epithelial stem cells in mouse and human skin, contributing to radiation dermatitis.

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 study found that lineage-restricted loss of p63 in murine thymic epithelial cells resulted in severe thymic hypoplasia and absence of hair follicles, indicating p63's critical role in thymic and hair follicle development.

The researchers reported that using a concentrate of conditioned mesenchymal stem cells derived from the placenta accelerated wound healing and regeneration in laboratory animals with severe local radiation injuries.

The authors concluded that thymoma-associated paraneoplastic syndrome in cats may manifest as noninflammatory alopecia instead of exfoliative dermatitis, and should be considered when diagnosing multifocal noninflammatory alopecia.

This study found that bulge keratinocytes in mice develop resistance to glucocorticoid treatment more slowly than interfollicular keratinocytes and do not significantly aid in repairing glucocorticoid-induced skin atrophy within five days.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.
