  • (15) Activin A, which was purified as the erythroid differentiation factor, accelerated the maturation of not only follicle-enclosed oocytes and oocyte-cumulus complexes, but also denuded oocytes, as measured by an increase in the percentage of oocytes with germinal vesicle breakdown (GVBD).
  • (16) Immunostaining for dimeric activin-A occurs in granulosa and cumulus cells of human ovarian follicles and in granulosa-lutein cells of the human corpus luteum.

  • (18) The results strongly suggest that the cumulus oophorus expansion-promoting action of granulosa cells is mediated by PGE2, and support the hypothesis (Downs and Longo, 1983) that granulosa cells might play a similar role in the mechanism of cumulus expansion in vivo.
  • (19) Adenosine (ADO) in low micromolar levels and hypoxanthine (HYP) in millimolar levels have been shown to inhibit maturation of cumulus-enclosed oocytes.
  • (20) This factor produced by porcine cumulus cells negatively influenced maturation of bovine oocytes; however, a similar effect was not demonstrated in the mouse.

Heap


Definition:

  • (n.) A crowd; a throng; a multitude or great number of persons.
