The polyovular follicles and amitotic divisions of ova in cats

猫的多卵卵泡与卵细胞的无丝分裂

In prokaryotes the nuclear material is simply a circular strand of DNA, not complexed with histone proteins, and cell division is amitotic.

在原核生物中，核物质仅是一个简单的环状DNA，而不与组蛋白结合，并且细胞为无丝分裂。

Results: The obvious amitotic phases and cellular senescent characteristics were observed in adult goat ventricular muscle cells including working and conducting cardiac muscle cells.

结果：正常成体羊心室心肌细胞，包括工作心肌细胞和传导心肌细胞，均可见明显的无丝分裂相和细胞死亡特征。

Conclusion: The neurons differentiated by NGF in cultured PC12 cells can divide in amitotic way.

结论：NGF诱导PC12细胞分化的神经细胞能以无丝分裂方式增殖；

CONCLUSION: Human amitotic membrane is a good carrier of keratinocytes cultured on it in vitro, and is able to promote the proliferation of keratinocytes significantly.

结论：人羊膜是角朊细胞在体外培养的良好载体，对角朊细胞有明显的促增殖作用。

In exponential proliferating 24-72h, many amitotic figures appear but the mitotic figure is not observed.

在细胞呈指数生长的24～72h时出现许多无丝分裂像，但未见有丝分裂像；

Results: Amitotic phases were observed in endothelial cells of normal adult goat and human heart.

结果：正常成体羊与成人心脏均发现内皮细胞无丝分裂相。

Results: chondrocytes exhibited various types of amitotic figures.

结果：软骨细胞呈现多种方式的无丝分裂像；
