From protein composition variance between the cell wall of resting cell of the ciliates and the remaining cell wall after the ciliates excystment, we infer that cell wall of resting cell of the ciliates possibly contains "active" components associated with life activity of the resting cell.

根据纤毛虫休眠细胞的包囊壁和细胞脱包囊后残留的包囊壁两者蛋白组成的差异推测，前者包囊壁可能含有与休眠细胞生命活动相联系的活性成分。

If the surroundings then turn to be benefit for its vital movement, it will go through excystment and become a vegetative cell again.
