This study suggests that the Leptin receptor may serve as a novel cell surface marker for dermal papilla cells, potentially aiding future isolation and research efforts in hair follicle regeneration studies.

This study reported that spironolactone at 200 mg/day significantly improved facial hair growth in women with hirsutism and showed a sustained reduction in ovarian androgens over one year.

This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.

This study found that women with androgenetic alopecia or alopecia areata have significantly lower serum ferritin levels than those without hair loss, suggesting a potential link between these types of alopecia and decreased iron stores.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

This overview discusses primary cicatricial alopecias, focusing on lichen planopilaris, and highlights the challenges in treatment and the progressive nature of hair loss despite symptom management, without providing new clinical results.

This study concluded that daily treatment with 1 mg finasteride did not affect spermatogenesis or semen production in young men and had small, reversible effects on prostate volume and serum PSA.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.

In this study, ACF sponges with 10% fucoidan significantly promoted wound healing and hair follicle regeneration in rats, showing improved hemostatic and antibacterial performance compared to other formulations.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This study found that prostaglandin metabolism enzymes are present in human hair follicles, suggesting a potential role in hair growth and differentiation, with some expression differences between men and women.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This research reported that squarticles, nanoparticles made from sebum-derived lipids, enhanced the follicular delivery and skin accumulation of diphencyprone and minoxidil, indicating effective drug deposition with reduced systemic absorption in alopecia treatment.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.
