Annulate Lamellae in The Embryonic Cells and The Graft Callus of Angiosperms

被子植物胚性细胞及嫁接愈伤组织中的环状片层

To observe the morphological changes of apoptotic cell nucleus and annulate lamella in spleen of chick embryo .

目的：着重观察鸡胚脾脏凋亡细胞核及其环孔板的形态学变化。

Annulate lamellae consist of parallel flat sacs with a length of 1.5 & 2.0 μ m.

环层板是由长1.5～2.0μm、平行排列的扁囊组成。

The ultrastructure and formation process of the annulate leamellae ( AL ) in mouse spermatids were observed .

本研究观察了小鼠精子细胞内环孔板的超微结构和形成过程。

Except in oogonium stage , annulate lamellae frequently appear in the ooplasm distal away from the nucleus .

除了在卵原细胞以外，环礼片层一般都分布在远离细胞核的卵质中。

According to the evidence which have been observed , it is proposed that annulate lamellae in goldfish oocytes are probably differentiated from the rough endoplasmic reticulum .

我们从观察结果推测金鱼卵母细胞的环孔片层可能是由粗面内质网衍生而成。

The results showed annulate lamellae appeared only during 8-18 stages of spermatid , and did not seen in spermatogonia , spermatocytes and early stage spermatids .

结果显示，环孔板仅在精子细胞变态的第8～18期可见；

Most of the annulate lamellae in mouse spermatids were continuous with a special type smooth endoplasmic reticulum ( SER ) & chrysanthemum-like SER ( cSER ) .

环孔板均与一种特殊形式的菊花状平滑内质网（cSER）相连。

Conclusion : The annulate lamella participates in the process of apoptotic nuclear fragmentation and wrapping nuclear fragments , which help to illustrate that the process of apoptotic nucleus split into nuclear fragments to form apoptotic bodies is an active process .

结论：环孔板参与凋亡细胞核的分割以及核碎块的包裹，提示凋亡细胞核裂解成为核碎块形成凋亡小体的过程是一个主动的过程。

From 20 days to 70 days of pregnancy there were numerous lipid droplets , from 70 days to 180 days they decreased regularly hut smooth endoplasmic reticulum increased from 20 to 180 days with typical morphology of annulate lamellae .

在妊娠20～70天时，脂滴相当多，在妊娠70～180天，脂滴逐渐减少；而滑面内质网的数量在妊娠的20～180天渐进性增加，呈典型的环层板状结构。
