Developmental potential of porcine nuclear transfer embryos derived from transgenic fetal fibroblasts infected with the gene for the green fluorescent protein: comparison of different fusion/activation conditions.
The in vitro developmental potential of porcine nuclear transfer (NT) embryos was evaluated. Oocytes were matured for 42-44 h, and metaphase II-oocytes were enucleated. Fetal fibroblasts infected with the enhanced green fluorescent protein (EGFP) gene were serum-starved for 3-5 days. A single cell was injected into the perivitelline space of the enucleated… CONTINUE READING
