When the embryos are only eight cells large , an embryologist very carefully makes a hole in each shell , and sucks out a single cell to be tested genetically .

在胚胎还只有8个细胞大小的时候，胚胎学家仔细地在每个细胞壁上开一个洞，然后吸出一个单细胞做遗传学测试。

Eggs of varying quality from my uterus this morning , it took pain meds , a doctor , nurses , a catheter , an ultrasound machine worth more than my house , a microscope , and an embryologist .

不同质量的卵子，花费了很多精力，包括：止痛药，一位医生，很多护士，一台价值相当于我的房子的超声波仪器，一台显微镜和一位胚胎学家。

Several days later , the embryologist looks at her petri dishes under a microscope to see whether any of the eggs has transformed into a blastocyst-the cluster of five cells that will eventually divide and divide again until it becomes a baby .

几天后，那位胚胎学家在显微镜底下观察灭菌盘，看看是否有卵子变成了胚胎就是五个细胞组成的一簇组织，它们最终会不断分化直到变成婴儿。
