October 2025 in “Records of Natural Products” This research found that kaempferol, a flavonoid from hair growth-promoting plants, significantly enhanced human dermal papilla cell proliferation and inhibited specific signaling pathways, outperforming minoxidil, with topical application in mice promoting hair growth and thickness, indicating potential as a natural hair loss treatment.
April 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” This study in mice suggests that defects in hair follicles with mesenchymal TSC2 disruption may result from an impaired TGFβ1 response, indicating a potential novel treatment approach for tuberous sclerosis complex.
August 2026 in “Clinical Cosmetic and Investigational Dermatology” This study highlights the potential of stem cell-derived extracellular vesicles to treat UV-induced skin damage by modulating key signaling pathways, though challenges like EV composition variability and skin barrier penetration remain, underscoring the need for further research into optimized delivery methods for effective therapies.

July 2015 in “Gene” This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.
January 2026 in “Molecular Nutrition & Food Research” This study found that Gynostemma pentaphyllum hydrodistillate and Damulin B exert significant anti-photoaging effects in UVB-irradiated models by reducing oxidative stress, improving ECM integrity, and enhancing skin hydration and elasticity.
