Maturation-promoting factor (abbreviated MPF, also called mitosis-promoting factor or M-Phase-promoting factor) is the cyclin-Cdk complex that was discovered first in frog eggs. It stimulates the mitotic and meiotic phases of the cell cycle. MPF promotes the entrance into mitosis (the M phase) from the G 2 phase by phosphorylating multiple proteins needed during mitosis.

The folded cortex of the growing oocyte of the frog extends as microvilli into the substance of the developing vitelline membrane and, internal to the folds, possesses a layer of cortical granules.
Free ribosomes, smooth-walled vesicles, coated vesicles, tubules, and electron-opaque granules are abundant in the peripheral zone of the by: Immature oocytes of the Rana perezi frog were studied electrophysiologically to see if some of the unusual ionic channels found in Xenopus oocytes were also expressed in these cells.
Growing oocytes showed a fairly linear current/voltage relationship (from – to +60 mV), whereas fully grown cells had several voltage-dependent by: Abstract.
Seven nuclear lines derived from erythrocyte nuclei of Rana pipiens were produced by serial nuclear transplantation into oocytes and eggs. Even at the termination of the experiments, embryos and tadpoles developed in the eighth transplant generations. Thus, there was no evidence that the mitotic progeny of the erythrocyte nuclei lost their Cited by: Oocytes of Rana pipiens exposed to exogenous progesterone in order to induce maturation have been observed to extensively metabolize this hormone.
When progesterone was injected directly into the oocytes, they did not mature, but similar metabolism of progesterone occurred.

BACKGROUND. The oocyte is the cellular precursor for the development of specialized cells. Oocytes from the South African clawed frog Xenopus laevis provide the most commonly used oocyte model for studying the properties, organization, and cellular roles of Ca 2+-permeable channels and experimentalists, the Xenopus oocyte brings together in a single cell the capacity to.
Rana pipiens Schreber, Northern Leopard Frog. James C. Rorabaugh 1. Historical versus Current Distribution. Northern leopard frogs (Rana pipiens) occurred historically from Newfoundland and southern Québec, south through New England to West Virginia, and west across the Canadian provinces and northern and central portions of the United States to British Columbia, Oregon, Washington.
We exposed R. pipiens larvae to different concentrations of atrazine (0, or 25 parts per billion, p.p.b.) in the laboratory by immersion (30 larvae per treatment; n = 3) from just after Cited by: Scientists in the field have conducted their research primarily by cloning metazoan nuclei into enucleated oocytes, a procedure developed originally in the leopard frog (Rana pipiens) by Robert Briggs and Thomas J.

Abstract. For more than 30 yr, Xenopus laevis has been the animal of choice for studying the biochemical regulation of the meiotic and early mitotic vertebrate cell cycles. Attracted by its diploid genome, several laboratories have begun using the similar, although evolutionarily distinct, frog Xenopus tropicalis for studies of vertebrate development.
