达尔博士及其同事的制做方法是由平滑肌细胞开始。
Smooth muscle is different from the familiar sort that cloaks bones and enables bodilymovement.
平滑肌不同于我们熟悉的那种包覆骨骼并使身体运动的肌肉。
It is a component of organs such as the gut and the blood vessels that sometimes need tochange shape while they are functioning.
它是肠道和血管等器官的组成部分,这些器官有时需要改变形状才能行使功能。
To make artificial blood vessels the team took smooth-muscle cells from fresh corpses andcultured them on tubular scaffolds made of a material called polyglycolic acid.
为了制造人造血管,这个小组从新鲜尸体上采集平滑肌细胞,将其放在聚羟基乙酸材料制成的管式支架上培养。
Grown this way, smooth muscle secretes collagen, a structural protein that is, amongseveral other things in the body, an important component of the walls of blood vessels.
采取这种方式生长,平滑肌可分泌胶原,一种结构蛋白,是人体中除其它几种物质外组成血管壁的重要成分。
The polyglycolic acid degrades spontaneously over the course of a few weeks with theconsequence that it is, in effect, replaced by the collagen.
