blastocyst stage meaning in Chinese
胚泡期
Examples
- 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。 - In mouse embryos , grp78 has been identified as early as the 2 - cell stage , and high levels were i - dentified at the blastocyst stage
有研究表明grp78在生物体发育过程出现在受精卵两个细胞阶段，并且在胚泡中已有较高的表达水平。 - Inner cell mass ( icm ) of the blastocyst stage embryo and primordial germ cells ( pgcs ) of fetus are the mostly used materials for derivation of pluripotent stem cells
早期囊胚的内细胞团( innercellmass ， icm )和原始生殖细胞( primordialgermcells ， pgcs )是获得多能干细胞( pluripotentstemcell )的两种主要的材料来源。 - These interactions are primarily dependent upon the coordinated actions of ovarian progesterone and estrogen , moreover , many other factors , such as growth factors , cytokines , ecm , adhension molecules , oligosaccharides and proteases , regarded as local mediators , endometrium and embryo have also expressed some specific receptors , via intracellular signal transduction chains and express some key genes , making receptivity of the uterus and synchronized development of the embryo to the blastocyst stage
成功的植入是处于接受态的子宫内膜和具有侵入性的胚胎间的同步协调反应。植入过程受多种生长因子及其受体、细胞因子、粘附分子、蛋白水解酶、寡糖等的精细调控，通过胞内信号转导及关键基因的表达使子宫内膜发生一系列复杂变化。 - Using the hprt gene as a positive control , our result suggested that both the testis tissue and the male embryos from which sry transcription can be detected failed to yield any positive results of xist . female embryos at the pronucleus stage and 2 - cell failed to produce any positive result of sry and xist too . while since the 4 - cells period , xist is constantly transcribed until blastocyst stages
然后利用实验一确定的pcr条件，以hprt为阳性对照，用巢式rt - pcr对小鼠早期胚胎进行xist基因的转录分析，结果发现，转录sry基因的睾丸组织以及雄性胚胎，从受精卵发育到囊胚的过程中，基本上不转录xist基因；不转录sry基因的雌性卵母细胞和雌性胚胎，从出现原核开始，到发育至2 -细胞期的过程中， xist基因一直不转录，但是，从4 -细胞期开始，一直到孵化前囊胚阶段，雌性胚胎都转录xist基因。
