Stage-specific requirement of cysteine during in vitro maturation of porcine oocytes for glutathione synthesis associated with male pronuclear formation.
Protection of porcine oocytes against cell damage caused by oxidative stress during in vitro maturation: role of superoxide dismutase activity in porcine follicular fluid.
The kit was applied according to the manufacturer's instructions and results revealed an activity course during in vitro maturation very different from what was expected.
The animals were ovariectomized at selected time points according to the in vitro maturation intervals.
Factors influencing resumption of meiotic maturation and cumulus expansion of porcine oocyte-cumulus cell complexes in vitro.
This is caused by differences between in vitro and in vivo environments for oocyte maturation.
Such morphogenesis is normally achieved in vitro only in diphasic media.
Thus, the surfaces of schistosomes may acquire the property to resist in vitro cytotoxic mechanisms mediated by human complement.
