In this study, hair-follicle-associated pluripotent stem cell implantation improved functional recovery and reduced inflammation in a mouse model of intracerebral hemorrhage.

ROS may affect hair loss related to hormones.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This review discusses advancements in artificial skin for wound treatment and reports no new clinical findings; the authors highlight the potential of new biomaterials to enhance future skin replacement therapies.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

This narrative review explores how exercise might help maintain skin homeostasis disrupted by protein deficiency, potentially by promoting processes like increased collagen synthesis and stimulating anti-inflammatory effects, though the exact mechanisms are not entirely understood.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This article reviews mechanisms by which herbal ingredients may stimulate or inhibit hair growth, and it reports no new clinical findings while suggesting potential for developing hair loss treatments.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

In this study using rabbits, HA2 hydrogels made from cross-linked hyaluronic acid and polysaccharide promoted wound healing better than other treatments, reducing inflammation and scar formation.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This study identified specific miRNAs and mRNAs involved in the development of secondary hair follicles in cashmere goats, particularly noting a targeted relationship between chi-miR-30e-5p and DLL4.

This study investigated the effects of the 60% alcohol extract from Alnus sibirica and its active compound, oregonin, on hair health, observing anti-oxidative and anti-apoptotic benefits in human hair dermal papilla cells exposed to oxidative stress, suggesting potential as natural materials for hair loss prevention.

This study found that Nelumbinis Semen extract may promote hair growth and reduce hair loss by increasing VEGF and IGF-1 expression and decreasing TGF-β1 in human dermal papilla cells and mice.

This study found that small amounts of RNA present in horsehair roots can be used for molecular biological analysis, although detecting mRNA transcripts in the hair shaft is more challenging.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This study found that factors released by mesenchymal stromal cells can enhance the proliferation and migration of keratinocytes in vitro, which may contribute to improved understanding of their role in wound healing and potential applications in dermal regeneration therapies.

This study found that molecular differences in paracrine factors between balding and non-balding hair follicles may enhance understanding of androgen action in hair disorders and potentially inform better treatments.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This study found that callus extracts from apple 'Hirosaki' may improve collagen synthesis, hair follicle cell proliferation, and possess significant anti-inflammatory properties.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study investigated the effects of heat-treated Limosilactobacillus fermentum LM1020 on hair growth and reported increased hair density, improved cellular activity, and beneficial scalp microbiota changes in patients with androgenetic alopecia over 24 weeks.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study observed that gene expression differences in Rex rabbits with varying wool densities suggest the involvement of specific genes and signaling pathways, including Shh and Eph, in hair follicle development.

This study found that taxifolin glycosides isolated from Rhododendron mucronulatum showed promise for developing treatments for male pattern hair loss by inhibiting DHT production and enhancing hair growth-promoting factors.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.
