由于细胞向内移动囊胚形成胚囊或肠胚的过程。

The infolding of a portion of the outer layer of a blastula in the formation of a gastrula.

肠套''。'叠'。''在原肠胚形成过程中囊胚的外层的折叠部分

The formation of a gastrula from a blastula by invagination.

容膝空隙供容纳膝部的空间或空隙，如在桌下

The formation of a gastrula from a blastula by invagination.

今天，人们意识到，它不仅仅是路基，更是道路的重要组成部分。

It showed that in conditions of water temperature 20～21℃,salinity 20～30,pH 8.0～8.3,the fertilized eggs developed to 2-cell in about 2h,blastula stage in about 15h,gastrula stage 30h and the hatched out larva 152h after fertilization.

其结果表明：在水温20-21℃、盐度20-30、pH值8.0-8.3的条件下，受精卵受精后2h为2细胞期、15h为囊胚期、30h为原肠期、55h为胚体期、152h孵出仔鱼

Reducing cyp11a1 expression resulted in expanded ventral domain and reduced dorsal domain during gastrulation, although the embryos appeared normal at the late blastula stage.

在此，我们利用cyp11a1及hsd3b的反意股 morpholino来研究P5和P4在早期胚胎的功能。

Mouse blastula showed clear band in 24-72 hours, came out from cell membrane in 1 day. After 3-5 days, it become embryonic stem cell mass. At 7 days, the cell mass showed "bird nest" shape.

小鼠囊胚孵出透明带的时间为24~72 h，从胞膜中孵出约为1 d，3~5 d后可形成胚胎干细胞集落，7 d后集落呈&鸟巢&状。

Results shows that the earlier the treatment starts, the more the decrease of gsc expression in late blastula, the fewer the number of somites at 24 h, and the more severe the defects in axial mesoderm. This suggests that maternal TGF-βsignals are activated immediately after fertilization and such activation continues before the onset of zygotic gene expression.

为了确定斑马鱼中母源TGFβ信号的激活时间，本研究用50μM SB-431542在中囊胚过渡期前(即合子基因开始表达之前)的不同时期处理胚胎，随后观察胚胎形态和检测分子标记的变化。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.
