他们运用荧光染料分组标记了老鼠胚胎中的细胞组织，这样就方便了所需细胞的识别和提取。

They used colored fluorescent tags to identify the groups in question in embryos, allowing the correct cells to be harvested.

通过荧光显微镜可直接观察组织工程化肌腱上的细胞。

We could also observe the cells on the tissue engineered tendons by fluorescence image directly.

这样极大提高了开发生物荧光的可能性，因为这意味着“绿色荧光蛋白”不再必须被注射到组织中，取而代之的是，其基因序列可以被加入到活体的基因中去。

This expanded the possibilities for exploiting bioluminescence dramatically, because it meant that GFP did not have to be injected into tissue.
