This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This study observed that cells from androgen-sensitive areas like the beard and scrotum showed higher androgen receptor levels compared to those from non-balding scalp areas, supporting the role of dermal papilla in follicle growth responses to androgens.

This study suggests that keratin expression in keratoacanthomas resembles that in the upper part of hair follicles, implying a potential origin, but it is indistinguishable from squamous cell carcinomas in terms of keratin reactivity.

This study identified and isolated highly proliferative canine keratinocytes in vitro, finding that follicular keratinocytes showed distinct proliferative capacity and marker expression indicative of putative epithelial stem cells.

Scalp hair follicle cells help protect and heal skin in certain skin conditions.

This study systematically reviewed 43 articles on the role of fibroblasts, especially dermal papilla cells, in androgenic alopecia, identifying androgen signaling and related pathways as key drivers of hair follicle miniaturization, which supports targeting dermal papilla cell dysfunction as a therapeutic strategy.

This research consisted of a Phase I/II study on androgenetic alopecia where male participants received intradermal injections of HSC, with hair growth efficacy assessed through Trichoscan imaging, although no new clinical results are reported.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

This article reviews the effectiveness of adrenal cortex compounds E and F in treating various connective tissue disorders and reports no new clinical findings.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This study found that primary stem cells from concentrated growth factor can differentiate into adipogenic, endothelial, and neuronal lineages in vitro, suggesting potential for use in regenerative therapies.

This study shows that the Wnt-β-catenin pathway promotes TERT expression in both stem and cancer cells, linking tumorigenesis with pluripotency.

This study established a method for selecting human hair follicle stem cells through quick-adherence to collagen, and found that β-catenin plays a role in their proliferation and differentiation.

This study found that in a rat skin model, fat cells inhibited the proliferation of organoid hair follicle cells and fibroblasts but may have accelerated hair follicle cell differentiation.

This study found that plantar dermis matrix homogenate can partially restore the regenerative capacity of hair follicles impaired in culture, with CTHRC1 playing a critical role in this process.

This review discusses the biological characteristics and potential of epidermal stem cells in orthopedic regenerative medicine but reports no new experimental findings.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study concluded that label-retaining cells in mouse epidermis differ in their sensitivity to proliferative stimuli, influencing their division and potential transdifferentiation without consistently depleting their population.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

In this study, researchers observed that keratoacanthoma exhibits dynamic follicular differentiation throughout its stages, with changes in specific keratin expressions, and regressed lesions showing epidermal rather than follicular characteristics.

This study found that dendritic epidermal T cells and their exosomes enhance epidermal stem cell proliferation, accelerating wound re-epithelialization in the skin.

This study identified a novel MTS24-positive murine keratinocyte population with increased colony-forming ability, suggesting these cells may serve as a new reservoir of proliferative progenitor or stem cells in hair follicles.

This study suggests that human and mouse hair follicle stem cells may support nerve repair and provide a practical source of stem cells for neurological therapies.

In this case study, a 78-year-old Japanese woman with Cronkhite-Canada syndrome experienced mesenteric lymphadenopathy, which reduced in size after treatment with the corticosteroid prednisolone. This suggests that mesenteric lymphadenopathy, though uncommon in CCS, may respond to steroid therapy.

This study observed that epidermal growth factor significantly enhanced the growth of dermal papilla, dermal sheath cells, and fibroblasts in vitro, particularly benefiting dermal sheath cells.

This study found that epidermal stem cells are located in rats' hair follicle bulge regions, and the methods used to isolate and culture these cells in vitro are feasible.

This study reported that supplementing rat hair follicle stem cells with chick embryo extract enhanced their migration and proliferation, possibly promoting differentiation toward Schwann cells.

This study found that dedifferentiated corneal epithelial cells can revert to a stem-cell-like state, aiding tissue homeostasis and repair, with this plasticity limited to the epithelial lineage and enhanced by niche-derived cytokines.
