The best survuval rate of each stage thawed-embryos existed in groups of Zygote EDT3O-two-step method with I mm equilibration(66%), of Morulae EDT3O-two-step method with I mm equilibration(94%) and EDT4O-two--step method with 0.5 mm equilibration(94%), of Blastocyte EDT3O-two-step method with I mm equilibration(91%) and EDT4O-one-step method with I mm equilibration(91%).

总之，我们的研究表明，DET玻璃液冷冻方法是简单、经济而又高效的，冷冻小鼠各阶段胚胎都能获得较高的存活率，其中受精卵的EDT30二步法1分钟平衡组(66％)、桑椹胚的EDT30二步法1分钟平衡组(94％)和EDT40二步法0.5分钟平衡组(94％)、囊胚的EDT30二步法1分钟平衡组(91％)和EDT40一步法1分钟平衡组(91％)冷冻效果最好。

In terms of immunology, uterus is a special reproductive and immune organ. It shows immunological tolerance and immunological rejection respectively at the time of blastocyte implantation and parturition; blastocyte implantation is also concerned with the action of many cytokines and MMPs.

从免疫学角度来讲，母体子宫作为特殊的生殖免疫器官在胚泡着床和分娩时分别表现为免疫耐受和免疫排斥，这两个生理反转过程必然涉及基因的时空差别表达；胚泡植入又涉及大量细胞因子及基质金属蛋白酶的协同参与。

When electric fusion method was used for nuclear transfer, the fusion rate (46. 0%), cleavage rate (53. 9%) and blastocyte development rate (10.9%) of adult ear fibroblasts were significantly lower than that of fetal fibroblasts (64. 5%, 70.1%, 21. 6% respectively), fetal skin cells (71. 5%, 70.8%, 22. 1% respectively) and ovary granulosa cells (88. 2%, 79. 1%, 25. 5% respectively). There was no significant difference among other donor cells in the cleavage and blastocyst development rate of resconstituted embryos.

当用电融合法进行核移植时，成体耳部成纤维细胞的融合率（46.0％），卵裂率（53.9％）和囊胚发育率（10.9％）均显著低于胎儿成纤维细胞（64.5％，70.1％和21.6％），胎儿皮肤细胞（71.5％，70.8％和22.1％），以及卵巢颗粒细胞（88.2％，79.1％和25.5％）；另外三种细胞间的卵裂率，囊胚发育率无显著差异，但卵巢颗粒细胞的融合率显著高于胎儿成纤维细胞和胎儿皮肤细胞（88.2％vs 64.4％，71.5％，P＜0.05）。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.

背景：胚胎干细胞来源于发育早期囊胚的内细胞团，适当条件下能在体外维持未分化状态、正常二倍体核型及无限增殖能力，且具有多向分化潜能，能够发育分化成机体3个胚层的所有类型细胞。

In this paper, the effect of different size of immature embryo on embryogenic calli induction and regeneration of B.

试验主要以二穗短柄草未成熟胚为外植体，研究了胚的大小对愈伤组织的诱导和再生的影响。

Abstract〕Objective:To study the expression of BMP3 mRNA in human normal,carious and inflammatory pulp tissues.

既往，有学者采用免疫组织化学、核酸分子原位杂交技术，分别研究了BMP〔1〕和BMP-2A基因〔2〕在牙胚中的分布与表达，认为它们在牙胚的发育过程中有重要意义。

Seeds endotestal, with an abaxial chalazal knot and an adaxial raphe with 2 furrows, one on each side; embryo straight, small; endosperm oily, proteinaceous, copious, ruminate.

种子有内种皮，具有背面的合点结，以及正面的具有2槽的缝；胚直，小；胚乳油性，蛋白质状，丰富，嚼烂状。

METHODS: The different combinations of the biofilm were put on the surface of chick embryo chorioallantoic membrane.

将制备的生物膜置于正对观察窗的鸡胚绒毛尿囊膜表面的血管最少处，然后贴在鸡胚绒毛尿囊膜表面上，封口膜封闭假气室，继续孵育。
