Maturation-promoting factor (MPF) has been known to be produced in the cytoplasm of starfish and amphibian oocytes, where it triggers meiotic maturation. Cytoplasm obtained from maturing oocytes of either mouse or surf clam was found to induce maturation when injected into immature starfish oocytes.
## Abstract Fully grown oocytes of starfish __(Asterias forbesi)__ are normally arrested in the dictyate stage of meiosis within the ovary. Reinitiation of meiotic maturation in these oocytes appears to be induced as a result of the interaction of 1βmethyladenine (1βMA) with the oocyte surface. The
