Cellular and developmental biological aspects of bovine meiotic maturation, fertilization, and preimplantation embryogenesis in vitro.

Abstract excerpt

Cellular aspects of reinitiated meiosis, fertilization, and early preimplantation embryogenesis in the bovine species were examined under in vitro conditions. An analysis of the cytoplasmic distribution of mitochondria, lipid droplets and vesicles in over 5,000 living GV-stage oocytes, with subsequent examination by electron microscopy, indicated that the organization of cytoplasm was pleomorphic and that five...
