BACKGROUND: Compared with adult mesenchymal stem cells, yolk sac-derived MSCs of early embryo have stronger self-renewal capacity and plasticity. Moreover, they could differentiate into angioblast and hemopoietic stem cells during embryonic development and trigger embryonic angiogenesis and hemopoietic tissue development.

背景：与成体间充质干细胞相比，来源于早期胚胎的卵黄囊间充质干细胞有更强的自我更新能力和可塑性，且在胚胎发育过程中可分化为成血管细胞和造血干细胞，启动胚胎血管发生和造血组织发育。

被诱导的心肌细胞的判定除常规指标外，我们还用了心脏特异性引物β-MHC对不同收缩时间的心肌细胞总RNA进行RT-PCR扩增和RNA斑点杂交，发现该心肌细胞不仅具有正常心肌细胞的特性，而且在分化早期就高度地表达心脏特异性基因。

Broodstock wintered at at 2~5℃ were fed Nitzschia closterium (30×10^4~50×10^4 cells/mL) supplemented with Chlorella sp. and egg yolk and had a mortality of 1.9%, 4.0% and 9.98% during maturation-inducing. However, the broodstock wintered at below 0℃ were fed the same food and had an increased mortality of 15.87%, 18.8%, 26.27% and 32.07% during maturation-inducing, indicating that there is influence of water temperature on survival of the broodstock during wintering period.

1当水温为2~5℃时，越冬的亲贝在促熟中是以新月菱形藻（30~50万个／mL）为主要饵料，辅以小球藻、蛋黄等，死亡率分别为1.9%，4.0%，9.98%；在0℃以下的越冬亲贝，在促熟中使用同样饵料，则死亡率提高为15.87%，18.0%，26.27%，32.07%，说明亲贝在海中越冬时，水温的高低直接影响亲贝在升温促熟饲育中的成活率。
