Cytoplasmic maturation of bovine oocytes: Structural and biochemical modifications and acquisition of developmental competence
(ELSEVIER SCIENCE INC, 2009)
Oocyte maturation is a long process during which oocytes acquire their intrinsic ability to support the subsequent stages of development in a stepwise manner, ultimately reaching activation of the embryonic genome. This ...
Cytoplasmic droplet acting as a mitochondrial modulator during sperm maturation in dogs
Motility acquisition during sperm maturation and passage through the epididymis is closely related to mitochondrial function and appears to occur in parallel with cytoplasmic droplet (CD) migration. However, such mechanism ...
Role of roscovitine and IBMX on kinetics of nuclear and cytoplasmic maturation of bovine oocytes in vitro
(Elsevier B.V., 2007-05-01)
The 3-isobutyl-1-methylxanthine (IBMX) is able to prevent resumption of meiosis by maintaining elevated cyclic AMP (cAMP) concentrations in the oocyte, and roscovitine, a purine known to specifically inhibit MPF kinase ...
Morphological Study of the Cytoplasmic Droplets as an Index of Sperm Maturation in Black Bengal Buck (Capra hircus)
(Sociedad Chilena de Anatomía, 2010)
Effect of roscovitine and cycloheximide on ultrastructure of sheep oocytes
It is believed the temporary meiosis arrest with roscovitine or cycloheximide may improve the in vitro developmental competence of oocytes in different animal species. However, little is known about the effects of these ...
The use of transmission electron microscopy and oocyte transfer to evaluate in vitro maturation of equine oocytes in different culture conditions
(Elsevier B.V., 2006-04-01)
The current study evaluates the ability of equine oocytes matured in different conditions to undergo nuclear and cytoplasmic maturation.. After oocyte transfer, embryonic development was diagnosed at 1.5 and 90 days of ...
Evaluation of in vitro nuclear and cytoplasmic maturation of prepubertal goat oocytes
(Blackwell Publishing, 2007-09-01)
Nuclear and cytoplasmic maturation of human oocytes cultured in vitro.
(Elsevier B.V., 2004-09-01)
Cytoplasmic maturation of oocytes from bitches at different stages of the oestrous cycle
