This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This review discusses psychocutaneous syndromes, detailing their classifications and management strategies, but reports no new clinical findings; it underscores dermatologists' role in these cases.

In this study, Geranium sibiricum L. extract promoted hair growth in vitro with human dermal papilla cells and in vivo in mice, outperforming minoxidil by proliferating cells and stimulating growth factor expression, suggesting its potential as a hair growth treatment.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

In this study, Meis1 was found to regulate epidermal homeostasis and act as a proto-oncogenic factor in skin tissues, with differences in expression patterns between normal and tumor cells.

This study found that a novel proniosomal gel formulation of CoQ10 improved antioxidant levels and provided better skin protection against UV radiation compared to a conventional CoQ10 gel in animal models.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This study found that some synthesized heterocyclic derivatives showed promising 5α-reductase inhibitor, antiviral, and anti-tumor activities, surpassing several reference drugs in effectiveness.

In this study, fraction No. 3 of Oryza sativa bran extract demonstrated high unsaturated fatty acid content and significant 5α-reductase inhibition, suggesting potential for developing anti-androgenic alopecia products.

In this study, researchers demonstrated that in a mouse model, the stimulation of mammary tumor growth due to progesterone is primarily caused by its metabolite, 5αP, not progesterone itself.

This study found that treatment with vitamin D increased the expression of LL-37 through the vitamin D receptor in cultured sebocytes.

This study found that the less common CAG-rs4045402 and GGN-rs3138869 polymorphisms were more frequent in patients with post-finasteride syndrome and androgenetic alopecia, suggesting a genetic predisposition to AGA development.

This study found that SA-MS hydrogel released Mo4+ ions which promoted healing of disease-impaired wounds by enhancing cell proliferation and angiogenesis, and through its photothermal effects addressed skin cancer-impaired wounds in mice.

This study found that human adult dermal fibroblasts can express markers typically associated with neural cells, suggesting potential pitfalls in relying on immunophenotyping alone for cell identity verification.

This study examined variations in epidermal thickness and protein expression across different dog breeds, finding significant differences by anatomical site and breed, with associated mRNA and protein expression changes observed.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This article explores the impact of COVID-19 on aesthetic dermatology, focusing on ensuring the safety of dermatologists while maintaining adequate services during the pandemic, but does not report specific findings or outcomes.

This study suggests that the long noncoding RNA H19 helps dermal papilla cells maintain their hair follicle-inducing ability by activating the Wnt signaling pathway, potentially offering a therapeutic target for androgenetic alopecia.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study found that neurotrophin-4 regulates Cav3.2 T-current expression in D-hair neurons via TrkB receptor activation, highlighting its role in mechanosensitive function.

This review discusses the unique dermatologic needs and conditions affecting women of color, noting specific skin and hair conditions but reports no clinical results.

This study found that berry extracts, especially black raspberry extract, may have anti-aging effects due to their high antioxidant activities.

This study found that the ethyl acetate fraction of Hibiscus rosa sinensis petals significantly reduced serum glucose and glycated hemoglobin levels in diabetic rats, showing effects comparable to the standard drug metformin.

The skin acts like an endocrine organ, making hormones that affect skin diseases and respond to stress.

This study found that Alpha Lipoic Acid may help reduce cigarette smoke-induced skin damage in rats by improving collagen structure and reducing markers of oxidative stress.

This article reviews common dermatologic procedures, focusing on skin biopsy techniques, with no new clinical results reported.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.
