The cancer cells connected with angioblast cells, vascular endothelial cells and blood vessel walls in the whole process of angiogenesis. 其全过程中癌细胞突起直接与成血管细胞、血管内皮细胞及血管壁相连。
The electron microscopy showed that angioblast cells were found in transplanted tumor tissues on the 2nd day. 电镜显示,人肺腺癌移植瘤第2天出现成血管细胞;
On the 3rd day, the surrounding vessels could be seen grossly expending to the tumor surface and angioblast cells were found under electron microscope. 肿瘤生长第3天时,肉眼可见周围血管向移植的肿瘤表面延伸,电镜下观察在存活的癌细胞中可见血管母细胞出现。
