This review discusses transplantation of melanocyte stem cells for vitiligo treatment and reports no new clinical results; it suggests the procedure could be effective in reactivating melanocyte precursors for repigmentation.

This paper explores cell kinetics in human hair follicles, focusing on the proliferation rates of keratinocytes and dermal papilla cells, but provides no new experimental findings.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

This study introduces a new method to isolate stem cells from the hair follicle outer root sheath of equine skin, demonstrating that these cells, named eMSCORS, proliferate efficiently and can differentiate similarly to adipose tissue-derived MSCs, offering a promising alternative for equine veterinary applications.

This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.

In this research, investigators used in vitro models to study the Merkel cell-neurite complex and reported that mechanical stimulation, similar to gentle touch, can induce molecular changes that are potentially relevant to hair growth, thus contributing to the understanding of its underlying mechanisms.

This study discovered that the gene Tfap2b identifies a melanocyte stem cell population in zebrafish, essential for regenerating melanocytes with multi-fate potential into adult pigment cells.

In this study, the researchers introduced a mutation in mice to mimic Olmsted syndrome and found that the mutation caused hair loss due to impaired keratinocyte differentiation and depletion of hair follicle stem cells.

In this study, researchers found two distinct stem cell reservoirs in human hair follicles that require mesenchymal cells for stem cell proliferation.

This review explores hypotheses about hair follicle stem cell function in morphogenesis and cycling, highlights the importance of dermal papilla cells and signaling pathways, and provides no new clinical findings.

Basonuclin is crucial for hair follicle development and cycling in mice.

This study found that strontium cannot fully substitute for calcium in oat seedling root and root hair growth, though it may help mitigate toxic effects from other ions.

In human follicular cells, this study found that an Annurca apple-based dietary supplement may stimulate the production of hair keratins, suggesting potential benefits for hair growth.

This study suggests that IGF-I may mediate androgen-induced hair growth in outer root sheath cells cocultured with beard dermal papilla cells.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.

Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.

This study observed that in vitro cocultures of hair follicle cells with dermal fibroblasts or hair papilla cells enhanced proliferation and differentiation of outer root sheath cells but did not mimic hair-type differentiation.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

This study found that a phosphodiesterase 3 inhibitor promoted hair growth in human dermal papilla cells and stimulated anagen induction in mice, suggesting potential as a treatment for alopecia.

This study found that cells from the upper hair follicle exhibited more active growth compared to other segments in vitro, suggesting their potential as a source of hair follicle stem cells.

This study investigated the histogenetic relationship between basal cell carcinoma and hair follicles, revealing specific staining patterns of a monoclonal antibody in different skin tissues.

This study suggests that pilose antler extracts promote hair regrowth in androgenetic alopecia mice by activating the AKT and Wnt pathways, enhancing hair follicle stem cell proliferation.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

In this study, Panax ginseng extract and its ginsenosides were found to stimulate the proliferation of hair-related cells and promote the transition from the telogen to the anagen phase, enhancing hair-shaft growth by suppressing BMP4 expression in human dermal papilla cells.
