May 2022 in “Journal of Investigative Dermatology” Endothelial TLR2 is crucial for timely wound healing, but HFSC TLR2 is not needed.
January 2018 in “Bradford Scholars (University of Bradford)” SWI/SNF complexes are crucial for wound healing but not for hair growth.
April 2017 in “The FASEB Journal” Eating more vitamin A changes hair growth-related proteins in mice, affecting hair cycle stages.
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.
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.
April 2023 in “Journal of Investigative Dermatology” Covering a wound can stop hair growth by promoting scarring, but boosting a process called Wnt signaling can help hair grow back even when the wound is covered.
