Scientists have successfully grown functional skeletal muscle in the lab and, after implanting it into a mouse, have observed the tissue fix itself after an injury. The muscle can also contract and flex similar to native tissue, the researchers reported in PNAS last month (March 31). “This is the first time we’ve seen muscle fibers contract so strongly in the lab,” Nenad Bursac, a biomedical engineer at Duke University in North Carolina and one of the authors of the study, told Quartz. “It was comparable to the contracting forces you’d see in an actual mouse muscle.”…
