New approaches regarding the in vitro maturation of oocytes: Manipulating cyclic nucleotides and their partners in crime
(2017-01-01)
Several discoveries have been described recently (5-10 years) about the biology of ovarian follicles (oocyte, cumulus cells and granulosa cells), including new aspects of cellular communication, the control of oocyte ...
Ultrastructural characteristics of non-matured and in vitro matured oocytes collected from pre-pubertal and adult domestic cat ovaries
(2009-07-01)
The present study describes the ultrastructural characteristics of cat oocytes before maturation and after 12- and 24-h in vitro maturation (IVM). Oocytes were recovered from pre-pubertal and adult queen ovaries after ...

Immature oocyte quality and maturational competence of porcine cumulus-oocyte complex subpopulations
(Instituto de Histología y Embriología "Dr. Mario Burgos", 2009-12)
Porcine immature oocyte quality (i.e., that of live oocytes at the germinal vesicle stage) was evaluated according to features of the surrounding cumulus, aiming to establish maturational competence of different subpopulations ...
