Research subjects

In vitro maturation and fertilization of bovine oocytes collected from slaughterhouse ovaries. In vitro development of embryos (human, murine, bovine & porcine species). Cloning by nuclear transfer in the bovine species (Thesis, ULB 1995). Studies about oocyte competency (human & bovine species). Cryopreservation of gametes and embryos (human, murine & bovine species) and stem cells (SCs; human & murine species) by aseptic vitrification. Production of transgenic mammals by pronuclear injection and embryonic stem cells injection (rodents), by somatic cell nuclear transfer (bovine species) and by ICSI-MGT Method (pig species). (ICSI-MGT: intracytoplasmic spem injection – mediated gene transfer).
