1·Apopcell is specified by nucleus chromatin condensation, nucleus shrinks and DNA fragments.

凋亡细胞是以核内染色质的凝聚，核的皱缩及DNA的碎片化为特征的。

2·Apoptosis with nuclear chromatin condensation and fragmentation as well as cell shrinkage and the formation of apoptotic bodies were observed.

细胞表现为细胞皱缩、核质浓缩、核碎裂、细胞起泡以及凋亡小体形成等凋亡特征的形态学改变。

3·Results: For the neuron, we can find pyknosis of neuron, depolymerization of ribosome, accumulation of lipid droplets and lipofuscin, condensation of chromatin.

结果：在老年组，神经元固缩、核糖体解聚、胞浆内出现大量脂滴及脂褐素颗粒、染色质凝聚。

4·The morphologic results showed that BHK-21 cells infected by VSV appeared peripheral condensation of chromatin, partition of cytoplasm and nucleus into membrane and so on.

形态学观察结果显示， 水泡性口炎病毒感染BHK -21细胞的形态变化具有较典型的凋亡特征， 如细胞膜内陷、核染色质凝集边聚等；

5·Optical microscope observation demonstrated the formation of apoptotic bodies and the condensation of nuclear chromatin after DAPI staining.

光学显微镜下可明显看到形成的凋亡小体，经DAPI染色可以看到染色质凝集和碎裂。
