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.
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 2019 in “Journal of Investigative Dermatology” This study found that BMPs can counteract the inhibitory effects of androgens on hair follicle stem cell differentiation, highlighting their critical role in the pathway dysregulation seen in androgenetic alopecia.
