research PI3K/Akt Signaling Pathway Is Essential for De Novo Hair Follicle Regeneration

30 citations , April 2020 in “Stem Cell Research & Therapy”

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.
