Abstract
Bovine oocyte cytoplasm has been shown to support the development of nuclei from other species up to the blastocyst stage. Somatic cell nuclei from buffalo fetal fibroblasts have been successfully reprogrammed after transfer to enucleated bovine oocytes, resulting in the production of cloned buffalo blastocysts. The aim of this study was to compare the in vitro development of fetal and adult buffalo cloned embryos after the fusion of a buffalo fetal fibroblast, cumulus or oviductal cell with bovine oocyte cytoplasm. The fusion of oviductal cells with enucleated bovine oocytes was higher than that of fetal fibroblasts or cumulus cells (83% versus 77 or 73%, respectively). There was a significantly higher cleavage rate (P < 0.05) for fused nuclear transferred embryos produced by fetal fibroblasts and oviductal cells than for cumulus cells (84 or 78% versus 68%, respectively). Blastocyst development in the nuclear transferred embryos produced by fetal fibroblasts was higher (P < 0.05) than those produced either by cumulus or oviductal cells. Chromosome analysis of cloned blastocysts confirmed the embryo was derived from buffalo donor nuclei. This study demonstrates that nuclei from buffalo fetal cells could be successfully reprogrammed to develop to the blastocyst stage at a rate higher than nuclei from adult cells.
