Coupled with the increased demand for blood by the lactotrophs, the pituitary cells no longer receive enough oxygen to survive - resulting in ischemic necrosis.

加上泌乳细胞对血液的需求增加，垂体细胞因而无法得到充足的氧以维持生存，从而导致缺血性坏死。

All right, as a quick recap, in pregnancy the pituitary cells are getting just enough blood to survive because the lactotrophs increase in size and number, taking up more blood than usual.

好！快速回顾一下：在怀孕期间，脑垂体细胞仅能获得足够维持生存的血供，这是因为泌乳细胞的体积和数量都增加了，比平常需要摄入更多的血液。
