They separated thylakoids a part of the cell where light reactions take place in plants, from young spinach leaves.

研究团队从菠菜嫩叶中分离出参与光合作用的类囊体。

With the thylakoids implanted into the mice and exposed to light, the mice recovered. Their metabolism returned to normal.

研究人员将类囊体植入小鼠体内，并施加光照，小鼠的关节健康状况因此得到明显改善，细胞的合成代谢也恢复正常。

The scientists then wrapped the thylakoids with the cover of animal cells, which made the implanted thylakoids more acceptable to foreign bodies.

再用动物自身的细胞膜来包裹类囊体，借助这层伪装，让植入的类囊体更容易为相异的细胞所接受。
