June 2023 in “Journal of Cellular and Molecular Medicine” This study observed that tissue-engineered skin, using VEGF165 gene-modified cells embedded in astragalus polysaccharide-containing 3D printed scaffolds, enhanced early vascularization, and collagen and hair follicle regeneration, leading to improved skin repair in nude mice with full skin defects.
January 2026 in “China National GeneBank DataBase” This study found that human hair follicle-derived mesenchymal stem cells demonstrated enhanced wound healing capabilities compared to umbilical cord-derived stem cells in laboratory and animal models.
October 2025 in “Journal of Investigative Dermatology” Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.
July 2023 in “Research Square (Research Square)” In an in-vitro study, researchers found that a specific concentration of Aloe Vera combined with injectable platelet-rich fibrin (i-PRF) significantly increased hair follicle stem cell proliferation compared to Aloe Vera or i-PRF alone, indicating potential benefits for alopecia treatment.
September 2015 in “International Society of Hair Restoration Surgery” This article discusses the role of hair follicle stem cells in potential breakthroughs for hair cloning and follicular cell implantation, but reports no new clinical findings.
