March 2015 in “Journal of Investigative Dermatology” Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.
January 2012 in “Journal of Investigative Dermatology” The document presented various studies on hair and cutaneous development, revealing insights into hair biology and potential therapeutic targets for hair-related conditions. Key findings included the role of stem cells and their niches in hair regeneration, the impact of TACE/ADAM17 depletion on alopecia, and the expression of somatostatin in hair follicles. Research on genetic factors, such as CYLD mutants and P-cadherin, highlighted their importance in hair growth and pigmentation. Studies on hair aging identified genes involved in hair loss in women over 40. Additionally, the potential of keratinocyte precursors from iPS cells for hair follicle regeneration and the effectiveness of a parathyroid hormone analog in reversing chemotherapy-induced alopecia were explored. The document also discussed the role of cholesterol biosynthesis in cicatricial alopecia, the necessity of Wnt signaling for hair follicle initiation, and the effects of ATP-sensitive potassium channel blockers on hair growth. These findings collectively advanced the understanding of hair growth, alopecia treatment, and skin regeneration.
