This article reviews the interaction between sex hormone pathways and morphogenesis-related signaling in epithelial organ development, using a chicken model to propose testable hypotheses, but reports no new clinical results.

Bimatoprost can cause longer, thicker, darker eyelashes and eyebrows.

This review analyzes the potential mechanisms by which SARS-CoV-2 may exacerbate symptoms of benign prostatic hyperplasia and suggests a connection via ACE2 and androgen receptor pathways; it reports no new clinical results.

This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.

In this study, adipose-derived stem cells from superficial adipose tissue showed higher regenerative potential, and more macrophages were found in superficial than deep adipose tissue, potentially influenced by skin microbiota.

This study found that adapalene-loaded nanospheres in a hyaluronic acid gel enhanced skin penetration and were nonirritant, making them potentially suitable for treating acne on oily skin.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This study constructed a model to predict finasteride's inhibitory activity on 5α-reductase type 2 and calculated that a 1 μM plasma concentration, after 50 mg administration, matches prostate inhibition levels.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

This study found that nanostructured lipid carriers provided better skin-targeted delivery and drug loading for lidocaine than nanoethosomes, indicating improved local anesthetic efficacy in vitro.

TP0427736 may help treat hair loss by blocking a specific protein and promoting hair growth.

This study identified significant changes in the expression of nine proteins in the nucleus accumbens of rats treated with finasteride, suggesting potential novel targets for its neuropsychiatric effects.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This study found evidence suggesting that hypertrichosis may be an adverse effect of inhaled corticosteroids in children, although it does not always resolve after stopping treatment.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

The study found that a specific signaling pathway helps skin wounds heal faster but may lead to larger scars.

In this study, researchers identified a new dominant mutation in Hairless mice, called Pied, resulting from a deletion in the Adam10 gene, which causes freckle-like skin pigmentation by inhibiting melanocyte expansion.

In this case report, an ointment containing 1.24R-dihydroxyvitamin D3 was effective for treating follicular keratosis of the chin but did not provide lasting benefits after treatment ended.

This study found that extracellular vesicles derived from mesenchymal stem cells and umbilical cord blood plasma enhanced wound healing and reduced scar formation in mice, suggesting their potential as therapeutic agents for skin repair.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This study demonstrated that adding human adipose-derived stem cells to hair follicle germ-like aggregates significantly improved hair shaft generation in transplanted nude mice, suggesting a promising strategy for hair regenerative medicine.

This review discusses various targets for treating prostate cancer and benign prostatic hyperplasia and reports on recent studies of new compounds and 5α-reductase inhibitors, but provides no new experimental results.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

This study observed higher rates of H. pylori infection in vitiligo patients compared to those with telogen effluvium, though no significant association was found with vitiligo disease activity or pattern.

This study reports that long-term use of finasteride does not affect bone mineral density in men with benign prostatic hyperplasia over a four-year period.

This study found that transplanted cultured epithelium from adult rat sole keratinocytes can respond to growth signals from dermal papillae and form follicular structures, especially with dermis support.
