    <description descriptionType="Abstract">Adult granulosa donor cells used in the nuclear transfer (NT) procedure can result in cloned cattle. Subsequently, it may be possible to use the same cell type to produce cloned transgenic cattle. Therefore, this study examined the effect of genetic manipulation and serum levels in culture of donor granulosa cells on developmental rates and cell number of bovine NT embryos. A primary cell line was established from granulosa cells collected by aspirating ovarian follicles. Cells transfected with a plasmid containing the enhanced green fluorescence protein (EGFP) gene, and non-transfected cells were used for cloning between passage 10 and 15 as serum-starved and serum-fed donor cells. There were no significant differences (P &amp;gt; 0.1) in cleavage rates or development to the blastocyst stage for NT embryos from transfected (60.4 and 13.5%, respectively) or non-transfected (61.9 and 14.1%, respectively) and serum-starved (60.6 and 13.4%, respectively) or serum-fed (61.3 and 14%, respectively) cells. Development rates to blastocyst stage of embryos produced using cells at passage 15 (27.1%) were significantly higher than those produced with cells at passage 10, 11, and 13 (7, 11.5, and 14%, respectively, P &amp;lt; 0.05). Green fluorescence was observed at different intensity levels in all blastocyst stage embryos resulting from transfected donor cells. The results of the present study indicated that genetically modified granulosa cells can be used to produce transgenic NT embryos and primary transgenic adult cells at late passage may be more effective donor cells than earlier passaged cells.</description>
