Voorbeelden van vitro

• Production of transgenic goats by pronuclear microinjection of in vitro produced zygotes derived from oocytes recovered by laparoscopy.

• This has led inevitably to the development of laboratory-based models that simulate oral biofilms in vitro.

• In the present work we determined whether preantral follicle development in vitro also allows oocytes to acquire calcium signalling activity.

• Effects of porcine follicular fluid on male pronucleus formation in porcine oocytes matured in vitro.

• It is also impossible to effectively maintain adult helminths in vitro to test the efficacy of drugs.

• Tumor necrosis factor alpha decreases the viability of mouse blastocysts in vitro and in vivo.

• Thus, the surfaces of schistosomes may acquire the property to resist in vitro cytotoxic mechanisms mediated by human complement.

• Such morphogenesis is normally achieved in vitro only in diphasic media.

• This is caused by differences between in vitro and in vivo environments for oocyte maturation.

• Factors influencing resumption of meiotic maturation and cumulus expansion of porcine oocyte-cumulus cell complexes in vitro.

• The animals were ovariectomized at selected time points according to the in vitro maturation intervals.

• 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.

• Protection of porcine oocytes against cell damage caused by oxidative stress during in vitro maturation: role of superoxide dismutase activity in porcine follicular fluid.

• Stage-specific requirement of cysteine during in vitro maturation of porcine oocytes for glutathione synthesis associated with male pronuclear formation.
