November 2023 in “Frontiers in Medicine” The method effectively mimics shaving damage on skin for testing skincare products.
29 citations,
September 2012 in “Birth Defects Research” Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.
January 2023 in “International Journal of Molecular Sciences” 
October 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” FGF9 from certain T cells helps create new hair follicles during wound healing, which could potentially be used for hair loss treatments.
June 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” FGF9 from certain cells can trigger new hair growth during wound healing, but humans have fewer of these cells, which may limit hair regrowth.
June 2013 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” A substance called FGF9 from certain immune cells can trigger new hair growth during wound healing in mice, but humans may not have the same response due to fewer of these cells.
June 2007 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.
May 2007 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.
May 2007 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.
