January 2026 in “Journal of Dermatological Science” This research observed that Salvianolic acid B (Sal B) significantly promoted hair regeneration in vivo and in vitro, outperforming minoxidil in a mouse model of androgenetic alopecia, by activating Wnt/β-catenin and mTORC2/Akt pathways and upregulating MMPs and MAPKs.

October 2013 in “Molecular Biology of the Cell” This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.
July 2025 in “bioRxiv (Cold Spring Harbor Laboratory)” This study developed a potent Wnt surrogate with high specificity for the Fzd7 receptor in mice, promoting full hair follicle regeneration and robust hair growth, suggesting potential applications in tissue development and targeted regeneration.

December 2019 in “The EMBO Journal” This study found that the E3 ligases NEDD4 and NEDD4L regulate intestinal stem cell priming by degrading the LGR5 receptor, and their loss leads to increased Wnt activation and crypt proliferation, which in turn accelerates intestinal tumor progression in mice.
