胚胎发育

However, the mice were dead immediately after delivery and all the mice had defect in cerebral development similar to microcephaly.

於显微注射与胚胎转移后，成功产出的MLL基因转殖鼠都有头部畸型产生，初步判定为小头症伴随大脑发育障碍，同时小鼠於出生后立即死亡。

Results The microtome section of embryonic with paramesonephric duct were obtained.

结果 获取含不同发育天数中肾旁管的小鼠胚胎切片。

结果获取含不同发育天数中肾旁管的小鼠胚胎切片。

The results show that GSH can improve the development rate of morula or blastocyst (32.84%),and rate of blastocyst (26.35%).

这表明GSH对牛胚胎的发育有一定的保护和促进作用。

Partial or complete removal of cumulus before fertilization had no effect on fertilization rates of oocytes, but complete removal of cumulus impaired embryo development, leading to reduced morula/blastula rates.

受精前去掉山羊卵丘或者去掉部分卵丘对受精率没有显著影响，但是受精前完全去掉卵丘对于胚胎的后续发育有明显影响。

The results showed that water content decreased first, then increased in the gastrula stage of embryonic development, reached the highest content at the second phrase larvae stage and then began to decrease from the third phase larva stage. The content of lipid in the dry weight increased with the embryonic development stages, but decreased at intramembranous nauplius stage, the second phase larva, and the infant stage of larvae development. The rate of lipid in wet weight decreased and the content of C20:4w6、20:5w3 and C22: 6w3 decreased.

结果显示，黑斑口虾蛄在胚胎和幼体的发育过程中，水的体积分数先降低，至原肠胚期开始升高，到第二相幼体期达到最高，之后又有所回落；脂类占组织干重的比率呈升高趋势，但分别在膜内无节幼体、第二相幼体和仔虾蛄期略有降低；脂类占组织湿重的比率呈降低趋势；花生四烯酸、EPA和DHA的体积分数都呈降低趋势。

Results: Nephron thin segments were observed in the late stage of embryonic kidney and developed after birth.

结果和结论：细段出现于胚胎后期，生后逐渐发育完善。

Results Capillary has been found in the surrounding matrix before the neural canal closure.

结果 描述对脊髓血管胚胎各期的发育特征，分析脊髓纵裂畸形和椎体血管瘤伴发的脊髓动静脉畸形病例。
