　　Taking biopsies from adult volunteers, including the muscle cells of individuals with congestive heart failure and the frail elderly, and implanting those stem cells into mice, they have been able to demonstrate that they can grow muscle tissue that generates about 90% to 95% of the force of a normally functioning muscle fiber.

　　他们在成年志愿者身上采集活组织标本(包括充血性心力衰竭患者和体弱老年人身上的肌肉细胞)，然后把这些干细胞植入老鼠体内，得以证明他们培育出的肌肉组织大约可以达到机能正常肌肉纤维90%到95%的力量。

　　Dr. Vandenburgh estimates that the technique could be ready for human clinical trial testing within four to five years. The approach will be best for someone with a specific weakened muscle rather than someone with a disease that causes general muscle wasting, he says.

　　范登伯格估计，这项技术有望在四五年之内达到做人类临床试验的条件。他说，这一方法将最适合某些肌肉受损的人，而不是身患某种疾病、导致肌肉总体萎缩的人。

　　Early trials could target drooping eyelids, for example, by injecting the stem cells into the muscle around the eye. The hope would be for the healthy stem cells to migrate to the wounded tissue and regenerate it.

　　早期试验可能会以下垂的眼睑为目标，比如说向眼部周围的肌肉注入干细胞，希望健康干细胞能够进入受损组织，使之重新生长。
