Confocal laser scanning microscopy used to localize the hsp70 protein in oocytes and embryos revealed that the distribution of hsp70 in the ooplasm of immature and mature oocytes is unaffected by exposure to decreased or elevated temperatures and that this protein was closely associated with the meiotic spindle indicating its possible role in stabilizing this structure, hi eight-cell embryos derived under control conditions, hsp70 was evenly distributed in the cytoplasm but appeared as aggregates in some embryos exposed to elevated temperature.

此蛋白均匀地分布在两种细胞的胞浆中。此形态特点与减数分裂期纺缍体有关，由此表明hsp70在中期Ⅱ期，具有稳定这种结构的作用。在对照组8细胞胚中，hsp70均匀地分布在胞浆中，而在处理组一些胚胎内，hsp70则发生凝集。

The third period is the Jiamuhe group overmature dry gas in the late Jurassic Period to the early Cretaceous.
