This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This article reviews methods to enhance epithelial–mesenchymal interactions for hair follicle bioengineering but does not present new experimental results; it emphasizes optimizing combinations for successful regeneration.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study found that bimatoprost stimulated hair growth in both human scalp follicle cultures and mouse pelage in vivo, suggesting it might offer a promising treatment for scalp alopecias.

This review highlights the potential of ginseng and its metabolites in preventing hair loss, detailing their hair growth-promoting effects observed in numerous preclinical studies, and emphasizing the underlying mechanisms involved.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This review discusses the use of 5α-reductase inhibitors, particularly finasteride, for treating conditions like benign prostatic hyperplasia, male baldness, and hirsutism, and reports no new clinical results.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This study suggests that heparan sulfate is crucial for regulating hair follicle formation, cycling, and gland morphogenesis, with its ablation leading to continuous hair growth and increased gland activity in mice.

This review discusses the progress in tooth regeneration research and highlights the potential of spatial-temporal release of developmental factors, but it reports no new clinical findings.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.
