Insulin is one of the most important versatile hormones, and its functions include regulation of glycemia homeostasis, enhancement of anabolism, control of cell division and differentiation, and modulation of cell growth and development.

胰岛素是机体最重要的激素之一，它调节机体的血糖稳定、促进细胞代谢、调节细胞的分裂分化和生长发育。

Wilms tumors with unfaorable histology contain anaplasia – defined as the presence of hyperchromatic, enlarged nuclei (at least 3 times as large as blastemal nuclei), and multipolar mitotic figures.

如有细胞间变则提示Wilms'瘤预后不良，所谓细胞间变，表现为染色质粗糙，胞核增大（至少是后肾胚芽细胞核的3倍大小）以及多极性有丝分裂像。

Four different pathways of androgenesis have been observed:Pathway of vege...

在雄核发育的研究中，观察到有营养细胞发育途径，生殖细胞发育途径，营养细胞和生殖细胞混合发育途径，以及均等分裂发育途径等四种类型，并对这四种途径进行了讨论。

An anticlinal division results in the formation of anticlinal walls between daughter cells, allowing a tissue to increase its circumference.

细胞的垂周分裂导致子细胞间垂周壁的形成，组织因此增加其周长。

At the cellular level, auxin regulates cell division, extension, differentiation and differentiation.

在细胞水平上，生长素影响细胞的伸长、分裂和分化。

Our data support the notion that human follicle development can be achieved in vitro in a bio-engineered culture system.

结论我们的数据表明，人类卵泡在体外生物工程培养体系中是可以发育的，但仍需要更多的研究进一步揭示体外培养卵泡是否获得充分大小的卵母细胞，而且卵母细胞是否有能力恢复减数分裂和受精。

There was no abnormal behavior observed in meiotic chromosomes in carrot. It has simultaneous cytokinesis. There are nine bivalents (9II) at metaphase I, indicating it is a typical diploid species.

通过观察胡萝卜花粉母细胞的减数分裂过程，发现其行为正常，是同时型胞质分裂，中期Ⅰ有9个二价体(9Ⅱ)，为典型的二倍体物种。

Phase splitting means the explants after the induction of cell dedifferentiation through continuously split the process of proliferation of daughter cells.

分裂期是指外植体细胞经过诱导以后脱分化，不断分裂、增生子细胞的过程。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
