摘要:The presence of galactose α-1,3-galactose residues on thesurface of pig cells is a major obstacle to successfulxenotransplantation. Here, we report the production offour live pigs in which one allele of the α-1,3-galactosyltransferase locus has been knocked out. Thesepigs, were produced by nuclear transfer technology basedon clonal fetal fibroblast cell lines as nuclear donors forembryos reconstructed with enucleated pig oocytes.
