March 2024 in “Nanomaterials” This review article summarizes recent advancements in biomimetic scaffolds, highlighting their promise in tissue engineering and personalized medicine, particularly for skin and musculoskeletal system regeneration, while emphasizing the need for more extensive research to ensure their safety for human use.
January 2003 in “Zhonghua shaoshang zazhi” In this study, murine fetal epidermal stem cells successfully formed new hair follicle structures when cografted with folliculus pili cells in nude mice.
February 2026 in “Biochemical and Biophysical Research Communications” This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.
