This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

This study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

This study found that phenyl-imidazole sulfonamide derivatives, particularly ISCK03, inhibited c-kit signaling and promoted depigmentation in various experimental settings, suggesting potential use as skin-whitening agents.

This review discusses the adverse effects of dermatological drugs, topical agents, and cosmetics, reporting no new clinical findings; the authors highlight several concerns such as cancer risk from hair dyes and systemic absorption issues with minoxidil.

In this study, keratin hydrogels derived from human hair were found to significantly enhance nerve regeneration in a mouse model, acting effectively as scaffolds by influencing Schwann cell behavior.

This study observed that key signaling events controlling hair growth in ferret follicles occur between 0 and 4 days after melatonin implantation, highlighting distinct processes in follicular regeneration and fibre growth.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study found that androgens increase Odc1 expression in skeletal muscle myoblasts, promoting proliferation and delaying differentiation.

This study found that Foxp1, a transcriptional factor, plays a key role in regulating hair follicle stem cell proliferation by modulating oxidative stress and the cell cycle during hair growth phases.

This study found that the synthetic retinoid EC23 effectively induces keratinocyte hyperproliferation and enhances hair growth in mice, showing more potency than all-trans retinoic acid.

In this study, dihydrotestosterone increased proliferation and decreased IL-6 production in in-vitro fibroblasts from hereditary gingival fibromatosis and normal gingiva, effects partially reversed by anti-androgens.

This study demonstrated that the highly divergent WDSV rv-cyclin significantly stimulates eukaryotic cell proliferation, leading to hyperplastic skin lesions in transgenic mice.

This study found that all-trans retinoic acid (ATRA) inhibits proliferation and promotes apoptosis in secondary hair follicle-derived dermal papilla cells from cashmere goats, likely via the TGF-β2/Smad2/3 signaling pathway.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

In this study, compound glycyrrhizin promoted hair regrowth in a testosterone-induced alopecia mouse model and increased human hair dermal papilla cell proliferation, likely through activating the Wnt/β-catenin pathway.

This study in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

The researchers reported that Gambogic Amide may prevent hair greying and promote hair growth by maintaining follicle pigmentation in vitro through activation and migration of melanocytes.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study reported that an ex vivo organ culture system effectively induced aging-related changes in healthy human skin, allowing testing of senolytics like tretinoin, resveratrol, and caffeine.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

Thyroid hormone may be useful for treating various skin conditions and needs more research.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

A specific gene mutation causes complete hair loss in an Irish Traveller family.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

In this study, researchers found that human fingerprint ridges are formed through a modified hair follicle developmental process and spatial patterns influenced by specific signaling pathways.

This study reported that deleting the MED1 subunit from the MED complex in keratinocytes resulted in disrupted hair differentiation and cycling, leading to hair loss in mice.

This review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.
