It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.
血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。
-
The first passage of YS-MSCs which grew in good condition was obtained, and adipogenic differentiation of YS-MSCs was induced by dexamethasone and insulin, and angioblast was induced by vascular endothelial growth factor and basic fibroblast growth factor.
取生长状态良好的第1代细胞，以地塞米松、胰岛素定向诱导卵黄囊间充质干细胞向脂肪细胞方向分化；以血管内皮生长因子和碱性成纤维细胞生长因子体外诱导其向血管内皮细胞方向分化。
-
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。
-
By comparison, the hemogenic endothelium is proposed to characterize the generation of hematopoietic stem cells from mature endothelium in the PSp/AGM region.
在卵黄囊和PSp/AGM区，造血和内皮细胞的发育关系分别表现出不同的特点：二者在卵黄囊共同来源于成血血管细胞；在AGM区则更多表现为生血内皮的模式。

There was no typical Golgi complex in oogonia, but there were some Golgi vesicles. At the early stage of vitellogenesis, Golgi complex was abundant whose saccules increased to more than ten layers. At the middle stage of vitellogenesis, Golgi complex grew more in numbers and got together, so its secreting quickened. Moreover, it formed a number of Golgi vesicles, which were filled with granule substances that changed into yolk granule finally.
卵原细胞内无典型的高尔基复合体，但具高尔基囊泡；卵黄发生早期，高尔基复合体发达，膜囊数达10多层；卵黄发生中期，高尔基复合体分泌活动加快，产生大量的大小囊泡，囊泡内充满颗粒状物质，最后演变成卵黄颗粒。

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.
在每年的3月-8月期间性腺处于Ⅱ期，此期精巢中精原细胞明显增多，胞质局部可见有线状的生殖质存在，平均成熟系数为0.037％；卵巢中以2时相卵母细胞为主，可见细胞质中出现强嗜碱性的卵黄核，细胞外由一层滤泡细胞包围，但尚无放射带，平均成熟系数为1.95％。9月-10月期间性腺处于Ⅲ期，此期精巢中仍有大量精原细胞，同时可见部分精母细胞，平均成熟系数为0.086％；卵巢中以3时石鲜孟加限加$玩印面n洲匆s性腺发生、分化及发育的周年变化相卵母细胞为主，细胞质中的卵黄核己消失，平均成熟系数为3.35%。11月性腺处于IV期，此期精巢内精细胞正处于不同的形成过程中，平均成熟系数为0.93%；卵巢中以4时相卵母细胞为主，胞质中充满染成桔红色的卵黄颗粒。

animal pole：动物极
卵黄相对多的一端称为植物极(vegetal pole),另一端称为动物极(animal pole). 雄性生殖细胞称为精子,精子个体小,能活动. 精子与卵结合为一个细胞称为受精卵,这个过程就是受精(图3-3). 受精卵是新个体发育的起点,由受精卵发育成新个体.
