Duke University researchers and other scientists are making strides in growing muscle in the lab that not only repairs itself but exhibits strength similar to that of normal muscle.
Duke University这幅放大影像显示了植入老鼠体内两周之后的实验室肌肉纤维。这些纤维通过染色标明了不同的蛋白。杜克大学(Duke University)的研究人员和其他科学家在利用实验室培育肌肉方面取得了很大的进展。这些肌肉不仅自我修复,还展现出与正常肌肉相近的力量。
Using lab-grown muscle could one day help people with certain muscle injuries, including accident victims with big gashes that lead to significant scar tissue. Engineering muscle that works like natural tissue could also accelerate the testing of new drugs: Scientists could use this tissue in place of animals.
有朝一日,利用从实验室培育的肌肉可能能够帮到有某些肌肉创伤的人,比如因为大伤口而长出明显瘢痕组织的事故受害者。制造出像天然肌肉一样发挥作用的肌肉,还有可能加快新药的测试,因为科学家可以用这类组织来替代动物。
Scientists have succeeded in developing ears, windpipes and livers, among other body parts, and even implanted some into humans. Muscle is among the more challenging because the fibers need to have the right structure and fit densely together. It must also be able to contract and exert force like natural muscle. And it needs good blood supply to cells, which can be difficult because muscle is very dense.
