Secret to scarless healing may lie inside our mouths
We all know that injuries which occur inside the mouth heal much quicker than those on the outside of the body. Scientists have a new understanding of why this is the case, and believe that their findings could one day be used in wound treatments that reduce or even eliminate scarring.
More specifically, the researchers analyzed the signaling pathways (interactions between cells) in the rodents' facial skin and in their oral mucosa – the latter is the protective inner lining of the mouth. "This data shows that the GAS6-AXL pathway is potentially important for scarless healing in the mouth and that manipulating it may help reduce skin scars as well," says Cedars-Sinai's Dr. Ophir Klein, co-corresponding author of a paper on the study. An experienced freelance writer, he previously obtained an English BA from the University of Saskatchewan, then spent over 20 years working in various markets as a television reporter, producer and news videographer.
