This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study reports that actively proliferating Lgr5+ stem cells in hair follicles do not appear to drive tumor formation in experimental skin carcinogenesis.

This study found that saw palmetto extract inhibits glioma cell proliferation and angiogenesis via the STAT3 pathway, suggesting its potential use as a complementary therapy for cancers with activated STAT3 signaling.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

This review examines recent research on hair follicle stem cells, focusing on their maintenance, differentiation, and the potential for new follicle generation, but it reports no new experimental results.

This study observed that skin stem cells in dogs could be identified using CD34 and CD200 markers, although further refinement in isolation and cultivation methods is needed for better identification.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

This study found that thymic stromal lymphopoietin (TSLP) promotes hair growth after skin injury by enhancing the proliferation of specific stem cells in hair follicles.

In this study, the researchers found that combining physical dermabrasion with chemical peeling increased growth factors and neuropeptides more than chemical peeling alone in porcine skin samples.

This meeting in Heidelberg highlighted diverse contributions on stem cell research, including pre-clinical and clinical applications, but reported no new experimental results.

This study found that in identifying bulge stem cells, CD34 is more specific in mice and CD200 in humans, with CD200 potentially marking progenitor and partially differentiated cells.

This report diagnosed a mass below a dog's eye as desmoplastic tricholemmoma based on histopathological and immunohistochemical findings.

This study reports the creation of a human dermal mesenchymal-like stem cell line from an androgenetic alopecia patient, which may serve as an in vitro model to explore alopecia mechanisms.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.

This study suggests that Isaria cicadae Miquel rice fermentation extract may enhance regenerative wound healing of hair follicles in mouse skin through the Hippo pathway mechanism.

In this study, researchers observed that deleting the Gpr54 gene accelerated the hair cycle and enhanced hair regeneration in mice by modifying the NAFTc3-SFRP1-Wnt signaling pathway, suggesting Gpr54 as a potential target for hair loss treatments.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

Pigs are a good model for studying human hair growth and disorders.

This study found that a combination of Ficus religiosa and Morus alba extracts promoted hair growth and Hair Follicle regeneration in a mouse model of hair loss by inducing the anagen phase and upregulating stem cell-associated genes.

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

This study observed that both TCA (35%) and GA (70%) chemical peels improved skin morphology and stimulated bulge stem cells in albino rats, with no significant difference between the two agents.

This study found that hair follicle stem cells are multipotent and can enhance nerve regeneration and function in mice, showing potential as an accessible source for treating peripheral nerve injuries.

This review discusses the life cycle and homeostasis of hair follicles, highlighting their development and the complex signaling between dermal and epithelial cells, but it reports no new clinical results.

This study found that extracellular vesicles from mesenchymal and outer root sheath stem cells may inhibit hair follicle stem cell apoptosis, suggesting potential therapeutic benefits for hair loss treatments.

In this study, researchers observed that hybrid secretomes most effectively stimulated proliferation and stem cell markers for hair regeneration in hamster skin, while human secretomes strongly activated the Wnt/β catenin pathway, suggesting different underlying mechanisms among the tested formulations.

In human hair follicle cultures, this study found that cyclohexyl salicylate, an OR2A4/7 agonist, promoted hair growth by delaying catagen development and expanding epithelial stem cell progeny, suggesting its potential as a non-drug hair loss treatment.
