June 2023 in “Nature” In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.
November 2025 in “Journal of Investigative Dermatology” AMP-303 injections can increase hair growth in androgenetic alopecia with minimal side effects.
