January 2022 in “Yokohama National University Repository (Yokohama National University)” This study found that exosomes from human dermal papilla cell cultures, particularly in an oxygen-permeable 3D environment, most effectively supported hair follicle stem cell maintenance and promoted hair follicle formation in vitro.
January 2022 in “Institutional Repositories DataBase (IRDB)” This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.
