1 Results: chondrocytes exhibited various types of amitotic figures.

2 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.

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

4 Results: The differentiated neuron appeared different patterns of amitotic figures such as transverse sever, longitudinal split, etc.

5 Results: The results showed that various types of amitotic figures could be found in the cells of capsule, zona glomerulosa, zona fasciculata, and zona reticularis of adrenal gland.

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

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

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