Mitogen-activated protein kinase translocates into the germinal vesicle and induces germinal vesicle breakdown in porcine oocytes.
That is, how long could the terminal release without exhausting its supply of vesicles?
The vesicles are filled with calcite, chlorite, quartz and carbon.
These vesicles which tended to have a central to basal distribution, occasionally filled almost the entire cytoplasm, but there was no evidence of circulation.
The preliminary study also indicated that vesicle-like formations, termed bladders, were produced in all test organisms.
Small electron-lucent vesicles were occasionally observed near these tips (fig. 16).
The non-granular areas contain numerous round, membrane-bound, electron-lucent vesicles.
The cell cytoplasm consists of few mitochondria, granules, endoplasmic reticulum, and vesicles.
