This study reports the successful generation of inducible pluripotent stem cells from mesenchymal stem cells derived from human hair follicles, marking a novel method of reprogramming these cells.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

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

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.
