September 2013 in “中国医师杂志” This study found that using serum-free Williams E medium was more effective for culturing human scalp hair follicles in vitro, suggesting it may improve hair follicle regeneration between hair transplant procedures.
This study reports that follicular cells isolated from murine skin can regenerate hair follicles after being injected into nude mouse skin, with the regeneration process relying on cell interactions, recipient sites, and cell numbers.
January 2011 in “The Chinese Journal of Dermatovenereology” In this study, DPC-hTERT cells were shown to induce hair follicle-like structures expressing specific keratin when co-injected with epithelial cells into nude mice.

February 2006 in “Chinese Medical Journal” This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.
January 2006 in “Chinese Journal of Dermatology” This study found that cultured dermal papilla cells can induce hair follicle regeneration and sustain hair growth both in vivo and in vitro, with their effectiveness linked to specific protein expression levels.
This study found that a hair follicle-like structure forms in nude mice when hair papilla cells are mixed with hair follicle epithelium and implanted, but not with dermal sheath cells or fibroblasts.
January 2003 in “Chinese Journal of Reparative and Reconstructive Surgery” This study found that dermal papilla cells and dermal sheath fibroblasts can induce hair follicle formation when combined with hair follicle epithelial cells, both in vitro and in vivo in nude mice.

December 1996 in “Journal of Investigative Dermatology” This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

November 1990 in “The Journal of Dermatology” This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.
