Pictoral abstract showing the use of nanofibers from fish collagen in wound healing. Image from Zhou et al., 2015.   Researchers in China have discovered that collagen isolated from the skin of tilapia effectively reduce wound healing time in mice. The usefulness of collagen, a major structural protein found in connective tussues, in wound healing has been known. Using fish proteins instead of typical mammalian sources reduces the risk for potential pathogens. Dr. Jiao Sun (Shanghai Jiaotong University School of Medicine) and colleagues isolated collagen from the skin of tilapia and spun…
You might be familiar with tissue regeneration in amphibians and reptiles where limbs can be fully regenerated following an injury. Until now, tissue regeneration following a wound was thought to be limited in mammals (ex: deer shed and regrow their antlers annually; some mice can regrow the tips of their fingers). Researchers discovered that African spiny mice are able to regrow skin, complete with hair follicles, after an injury. We are not talking about simple wound healing, but actual skin regeneration without scarring. Researchers suspect this unique ability may have evolved to help them…
