title: Presence of microtubules in isolated cortices of prophase I and metaphase II oocytes in Xenopus laevis.
abstract: An extensive array of microtubules has been shown to exist in the cortex of Xenopus laevis oocytes both at the prophase I and metaphase II stages. The cortical microtubules were visualized after the oocyte cortex was squashed and immunostained using anti-tubulin antibody. They are cold- and nocodazole-sensitive; their stability to both treatments decreases after meiotic maturation. Biochemical extraction of manually isolated oocyte cortices, in a microtubule-stabilizing buffer, confirms these cytological observations.
