Key points from article :
Cosmetic laser treatment and retinoic acid target the same pathway to regenerate hair follicles.
Loose pieces of self-noncoding double-stranded RNA (dsRNA) promoted this regeneration in mice.
Genetically modified mice to remove their toll-like receptor 3 protein.
Then gave retinoic acid to those mice and witnessed regeneration of follicles.
Opens the door for developing therapies to reduce visible skin aging, regenerate lost hair follicles following trauma.
