Different genes and pathways are active in yak skin and hair cells, affecting hair growth and immune responses.
Non-immune dermal cells dominate, epidermal cells increase after day 9, and certain immune cells persist beyond inflammation in wound-induced hair follicle regeneration.
August 2022 in “International Journal of Molecular Sciences” DNA methylation controls lncRNA2919, which negatively affects hair growth.
January 2022 in “Stem cell biology and regenerative medicine” New hair can grow at wound sites, which could help improve treatments for hair loss and wound healing.
