细胞发生

Moreover, the article discusses the mechanism by which promotes plant growth in detail by analysing the cell morpho genesis, expansion of cell wall and the cole of cytokeloton in cell elongation.

另外从细胞的形态发生、细胞壁扩展的机制和细胞骨架在细胞伸长中的作用等几个方面对油菜素内酯促进植物生长的细胞及分子生物学机制进行了详尽的论述。

The differentiation of the cells and the expression of Myosin Ⅶa were revealed by immunohistochemical staining.

结果脂质体介导的基因可在细胞内获得良好的表达，转染后24h，相差显微镜下观察细胞形态发生变化，免疫组织化学显示转染后细胞可以表达毛细胞特异性蛋白Myosin7a。

Methods: In order to study P〓、P〓 and bcl-2 gene expression and its significance in tumorgenesis of lung cancer, the expression of P〓、P〓 and bcl-2 gene was detected by RT-PCR, PCR-SSCP and immunhistochemistry SABC in 65 cases of lung cancer tissues, tissues adjacent to carcinoma and normal tissues, its correlation to clinico-pathological features and prognosis of lung cancer was explored.

因此人们预测其重要性不亚于RB和P〓基因，甚至比其更为重要。Bcl-2基因是继促进细胞生长的癌基因和突变的抑癌基因之后，近年来发现的第三类肿瘤基因，它是一种调控细胞死亡的"存活基因"，可抑制细胞的程序化死亡，故称之为细胞凋亡抑制基因，在肿瘤发生、发展中起着重要的作用。

The results show that, with the maturity of the gonad, the undifferentiated germ cell divided and differentiated to smaller oogonium or spermatogonia, and the oogonium or spermatogonia transformed to oocyte and sperm undergoing a series of maturation process.

摘 要 通过观察栉江珧的未分化生殖细胞，精原细胞和卵原细胞，精母细胞和卵母细胞，精子和卵子的形态结构与分布状况及核仁在卵成熟过程中的变化，对栉江珧生殖细胞发生及成熟过程的有关问题进行了探讨。

Vascular endothelial growth factor is an important angiogenine. There is accumulating evidence shows that expression of VEGF in mature chondrocyte can promote cell redifferentiation and caryocinesia activity. VEGF plays a key role for chondrocyte to survival and proliferation during the chondrogenesis.

对成熟软骨细胞分泌表达蛋白的研究发现，软骨细胞表达一定水平的VEGF以提高软骨细胞有丝分裂活性并促进其再分化，在软骨发生发育过程中，对软骨细胞的存活与增殖起着重要的作用。

Conclutions: Under ischemic condition, the decrease of Iks could prolong the mid-late repolarization phase of APD. It could cause EAD and then arouse TdP. Because the decrease of M cell was significantly greater than that of sub-endocardial myocytes and sub-epicardial myocytes, it could increase TDR. Cardiac arrhythmias could last due to reentrance that secondary the increase of TDR.

缺血时，心肌细胞的Iks电流减弱，使得细胞动作电位复极中后期延长，容易出现EAD并引发TdP；由于M细胞的Iks电流减弱程度明显大于心内、外膜细胞，造成心室跨壁复极离散度增加，有利于折返的发生，使得心律失常得以持续。

The spermatogenesis includes five stages: spermatogonium、primary spermatocyte、secondary spermatocyte、spermatid and spermatozoon.

雄体的生殖细胞发生经历精原细胞、初级精母细胞、次级精母细胞、精子细胞和成熟精子五个时期。

The spermatogenesis includes five stages: spermatogonium、primary spermatocyte、secondary spermaticyte、spermatid and spermatozoon.

雄体的生殖细胞发生经历精原细胞、初级精母细胞、次级精母细胞、精子细胞和成熟精子五个时期。

The spermatogenesis of Solen grandis included five stages: spermatogonium, spermatocyteⅠ, spermatocyteⅡ, spermatid and spermatozoon.

大竹蛏精子发生历经精原细胞、初级精母细胞、次级精母细胞、精细胞和成熟精子5个阶段。

Experiment on adaptation effects in cat striate cortex found no pronounced difference between simple cells and complex cells.

结果显示，相对于简单的平动刺激，复杂的光流刺激引起了更显著的适应及后效应：细胞的反应在适应期间及适应后衰减程度更大，多数细胞的方向选择性在适应后发生了显著变化；总体上，细胞对复杂光流的适应具有方向选择性，但细胞对平动刺激的适应与测试刺激的运动方向无关。
