November 2019 in “FEBS open bio” This study found that stimulating dermal papilla cells with specific adipo-osteogenic factors and growth factors helped maintain their viability and restored their hair-forming activity in vitro.
January 2024 in “Biomaterials Research” This study found that human hair follicle dermal papilla cells cultivated as 3D spheroids in hexanoyl glycol chitosan-coated dishes formed hair-like structures, with minoxidil enhancing growth, and successfully integrated into artificial skin models, suggesting advancements for hair loss treatments and skin restoration therapies.
