Proscar (finasteride) blocks 5α-reductase in sea urchin ovaries and testes, suggesting potential treatment for androgen-related conditions.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

This article describes telogen effluvium as diffuse cyclic hair loss in women caused by systemic stresses, diseases, or physiological situations, but reports no new clinical results.

Slug (Snai2) helps regulate hair growth timing in mice.

This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.

This review discusses the development of human skin with a focus on desmosomes, noting the challenges of translating animal model findings to humans due to species differences and limited human sample access.

This study found that the Ovol2-Zeb1 regulatory circuit is crucial for controlling directional migration and proliferation in epithelial cells, facilitating skin regeneration and repair in mice.

In this study, a missense mutation in the MAP2 gene was found to be associated with reduced hair follicle density, leading to the hairless phenotype in pigs.

Scalp skin condition LEDS has similar features to Zoon's balanitis, a mucosal skin disorder.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

Telogen effluvium is a type of temporary hair loss.

In this study, a dog diagnosed with both ehrlichiosis and demodicosis showed significant clinical improvement after receiving a treatment regimen of doxycycline, ivermectin, diphenhydramine, vitamin B complex, and sulfur soap baths, noticeable by the 14th and 28th days of therapy.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This study found that canine bulge-derived keratinocytes are highly proliferative and can reconstitute pilosebaceous structures, indicating their potential utility in studying human stem cell biology and hair disorders.

This case study describes a Lop male rabbit with Malassezia-associated dermatitis, initially treated with griseofulvin but requiring ketoconazole for complete recovery after recurrence.

This article describes the "naked" mouse mutation, which results in hair loss and is linked to chromosome 15, noting similarities and differences with human ectodermal dysplasia, but provides no new experimental findings.

Feathers become harder as they develop due to a change in keratin type.

This article discusses recent advances in understanding the mechanisms of tactile end organs in the epidermis and hair follicles from studies of mouse hairy skin, but it reports no new clinical results.

In this report, researchers describe a 13-month-old with neurodevelopmental disorder NEDESBA, confirming a TRAPPC4 gene mutation as the cause after excluding biotinidase deficiency, highlighting the importance of molecular testing for accurate diagnosis in overlapping metabolic and genetic conditions.

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

Advanced imaging techniques are crucial for accurately diagnosing Monilethrix, a rare hair disorder.

In this study, the researchers reported that Krox20 plays a crucial role in epidermal homeostasis and hair development, influencing stem cell maintenance and cell survival through the modulation of cellular pathways.

This review discusses the potential conflicts of interest and quality concerns associated with direct-to-consumer teledermatology platforms and reports no new experimental results.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This study investigates the effects of Tenebrio molitor as a novel biomaterial for preventing alopecia and promoting hair growth, but reports no conclusive results.

This study found that human C-tactile afferents respond to hair deflection, suggesting a functionally relevant anatomical relationship to hair follicles similar to that observed in mice.
