玉米胚乳细胞淀粉质体增殖有被膜出泡、外凸，以出芽方式形成淀粉质体；淀粉质体被膜缢缩形成淀粉质体；以中间隔板形式形成淀粉质体；淀粉质体被膜向内出泡，在淀粉质体内形成新的淀粉质体等几种方式。

Germ potential is established after conception in a totipotent zygote and retained subsequently during development in blastomers of morula , cells form the inner cell mass of blastocyst , epiblast and population of primordial germ cells .

种子潜能的确定是全能的受精卵形成之后，并且随后在桑葚胚，胚泡内层细胞，外胚层和原生殖细胞的发育过程中保留。

The researchers used fast neutrons to irradiate mouse embryos between the blastocyst stage and the beginning of somite formation .

研究人员用快中子照射在胚泡期和体节形成开始之间的小鼠胚胎。

Morula in the uterine cavity to continue cell division to form the blastocyst, about 6-8 days after fertilization into the endometrium, a process known as implantation or cultivation.

桑椹胚在子宫腔内继续细胞分裂形成胚泡，大约在受精后6—8天进入子宫内膜，这个过程叫做着床或种植。

Results:LIF improved the development rate of early embryo at the concentration of 0.1,1 and 10ng/ml(P.05).The enhanced effects of LIF were significant for morula and blastocyst stage,not for 1～8 cell stage of embryos.Conclusion:LIF may improve the development of early mouse embryos at the appropriate concentration.

结果：①0.1ng/ml、1ng/ml和10ng/ml浓度的LIF对小鼠早期胚胎的发育和胚泡的形成有促进作用，0.01ng/ml和100ng/ml浓度的LIF对胚胎的发育无明显影响；②LIF对小鼠早期胚胎发育的影响主要发生于桑椹胚和胚泡期，对1～8细胞期胚胎无明显影响。

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。

During peri-implantation, the decrease of the ECL and the PHA-L receptors may lead to the failure of implantation in the oviduct, and the increase of the UEA receptors at diestrus may contribute to the process of fertilization.

围植入期ECL和PHA-L受体表达下降，在输卵管内形成了不利于植入的微环境，可能是胚泡正常情况下不植入输卵管的原因之一；动情期UEA受体水平显著低于动情间期，有利于受精过程的正常进行。
