(b) 培埴细胞组织 在空间实验室环境中 可以在不受重力干扰的情况下培埴活细胞 美国国家航空和航天局(美国航天局)已为进行这种培埴研制出一种生物反应堆装置 在地球上模拟失重产生的影响 不过 这种装置仍受重力的限制 在空间站进行
(b) Tissue culture: Living cells can be grown in a laboratory environment in space where they are not distorted by gravity. The National Aeronautics and Space Administration (NASA) already has developed a Bioreactor device that is used on Earth to simulate, for such cultures, the effect of reduced gravity. Still, these devices are limited by gravity. Growing cultures for long periods aboard the Space Station will further advance this research;
