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.
