The researchers showed that a device with a number of these channels leading to a central reservoir, like spokes on a wheel, worked just as well separating cancer and non-cancerous cells. 研究者们展示了包含许多这样的通道的装置,这些通道最终汇集于一个中心贮存器,就像车轮的辐条,以分离癌细胞和正常细胞。
Because a rotating joint is essential to a wheel, a wheel made of living cells would twist its artery vein and nerve connections at the first revolution, making living impracticable. 因为一个旋转的接头对轮子来说是至关重要的,由活的细胞构成的轮子在第一次转动时便会扭伤其上的动脉和神经的连结,因而不现实。
