Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This study found that the petroleum ether extract from the leaves of Hibiscus rosa-sinensis demonstrated more effectiveness in promoting hair growth in rats compared to the extract from its flowers.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This study found that maternal PPARγ is essential for preventing the production of inflammatory lipids in mouse milk, which can otherwise cause inflammation, alopecia, and growth retardation in nursing pups.

This study found that Myc activation in epidermal stem cells leads to chromatin modifications that promote stem cell exit and differentiation, which can be influenced by HDAC inhibitors like trichostatin A.

In this study, thymosin beta4 was found to stimulate hair growth in normal rats and mice by affecting key processes in the hair follicle cycle, such as stem cell migration and extracellular matrix remodeling.

This study suggests that oxidative stress may contribute to androgenetic alopecia by inducing premature senescence and secretion of hair growth inhibitors in dermal papilla cells from balding scalp.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

This study concludes that fetal skin cells can significantly enhance wound healing and reduce scarring when used to treat severe burns and various wounds in children.

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

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study found that prevascularizing dermal matrices with adipose tissue-derived microvascular fragments improved vascularization and allowed earlier successful skin grafting in a bradythrophic wound model.

This study found that pubic skin fibroblasts respond to androgens, increasing 5α-reductase activity via an androgen receptor-mediated mechanism, suggesting its potential as a marker of androgen action in vitro.

This review discusses the use of platelet lysate and its growth factors in treating diseases and regenerative medicine but reports no new clinical findings.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This study found that mouse FLRG protein, a secreted glycoprotein, is expressed in certain tissues and plays a role distinct from follistatin during wound healing, suggesting different functions in vivo.

This study reported significant upregulation and release of S100A4 in psoriatic skin, which may actively contribute to psoriasis pathogenesis.

This study found that Eda and activin A regulate Foxi3 expression, which may contribute to the development of hypohidrotic ectodermal dysplasia by affecting Foxi3 activity in ectodermal appendages like hair and teeth.

This study found that isotretinoin, a drug commonly used for acne, inhibits polyamine transport in Trypanosoma cruzi, leading to trypanocidal effects, and suggests its potential as a treatment for Chagas disease without affecting mammalian cell viability.

This review discusses the challenges and potential solutions in studying Demodex mites and their possible pathogenic role in human skin disorders but reports no new findings.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.
