August 2008 in “Genes & Development” This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

January 2004 in “The International Journal of Developmental Biology” This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.
This study showed that exosomes from hyaluronic acid-primed induced mesenchymal stem cells promote hair growth by enhancing proliferation and migration of hair follicle dermal papilla cells and modulating key growth factors and signaling pathways, potentially counteracting the effects of DHT-induced hair loss.
April 2023 in “Journal of Investigative Dermatology” This study found that exosomes from hyaluronic acid-primed mesenchymal stem cells may promote hair growth in androgenetic alopecia by improving hair follicle cell function and restoring key signaling pathways disrupted by DHT.
