This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This study found that polymeric nanoparticle suspensions can deliver poorly water-soluble drugs to hair follicles in animal models, suggesting a promising method for targeted topical treatments.

This study reported that treating wounds with a hydrogel from acellular porcine adipose tissue and adipose-derived stem cells may significantly enhance wound healing and regeneration by promoting new adipocyte formation.

This study found that several synthesized pregnane derivatives exhibited significant inhibitory effects on testosterone conversion to dihydrotestosterone and reduced related androgenic parameters in multiple pharmacological models.

This review discusses dermatological issues in llamas, detailing common findings, parasites, and disorders, but reports no new clinical results; it highlights the need for recognizing normal skin variations and discusses potential treatments like zinc therapy for certain conditions.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This study found that English springer spaniels are predisposed to sebaceous adenitis with more severe clinical signs compared to standard poodles, and many affected dogs are euthanized due to the disease.

Finasteride effectively treats enlarged prostate and male baldness, improves symptoms of hirsutism in women, but doesn't work for acne, and may delay prostate cancer progression with few side effects.

The T-zone on the face has more androgen receptors and produces more oil than the U-zone.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

Androgen receptors found in monkey scalps, similar to humans, affect hair growth.

This study introduced a novel nonsteroidal androgen receptor antagonist that effectively controls sebum production in the golden Syrian hamster ear model through targeted follicular delivery.

This article discusses the complex interaction between androgens and the skin, highlighting elevated androgen levels in women with hirsutism, female-pattern hair loss, and acne, but reports no new clinical results.

This review discusses the potential of follicular drug delivery systems to target the pilosebaceous unit and reports no new research findings.

This review highlights that clascoterone, a newly FDA-approved topical androgen antagonist, effectively reduces both non-inflammatory and inflammatory acne lesions with no systemic effects, making it a promising new option for acne treatment in both male and female patients.

This study observed that using a relaxed suture technique on scalp incisions may prevent linear scars by reducing pressure on upper stem cells.

In this review, researchers explored how PGC-1α might improve aged skin barrier function by influencing mitochondrial function and reducing inflammation, factors that are linked to epidermal health during aging.

This review discusses the impact of testosterone therapy on postmenopausal women's sexual function and well-being but notes a lack of long-term safety studies and debates on defining androgen insufficiency.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This study reported that the use of composite RGDmix hydrogel improved the survival and proliferation of human amniotic mesenchymal stem cells and increased growth factor expression, enhancing wound healing through the RGDSP/integrin αv/PI3K/AKT signaling pathway.

The document concludes that scalp disorders can be treated with hair washing, specific shampoos, medications, and sometimes surgery or hair transplants, but hereditary baldness is untreatable.

In this study, researchers found that a composition containing mannose-6-phosphate significantly reduced the total skin pore area by 24% in women after 56 days and by 30.2% in men after 7 days, suggesting its effectiveness in improving pore appearance by targeting dermal and epidermal modifications.

This study found that a gene from hamster flank organs is indirectly regulated by androgens, despite lacking direct androgen responsive elements, indicating involvement of androgen-dependent transcription factors.

This study found that engineered skin substitutes made with skin-derived precursors and epidermal stem cells can regenerate hair follicles after grafting into nude mice.

This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

Minoxidil, a common hair loss treatment, might work by counteracting a hormone that reduces hair growth and promotes hair loss.

Androgens, like DHT, affect hair growth and treatments like finasteride may help.

This chapter reviews the role of the testes in producing and functioning of testicular androgens and protein hormones, but it presents no new clinical results.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.
