Two injection methods were examined for making chimeras between Chinese pigs (Meishan) and European pigs (Landrace or Landrace x Large White). Furthermore, mitochondrial DNA (mtDNA) polymorphism was detected as a cell marker for the analysis of chimerism. In the first experiment, blastomeres were transplanted into embryos at the 4-16-cell stage. Of 41 transplanted embryos transferred into 3 females, 12 were single-colored, but no overt chimeras were obtained. Judging from coat color and mtDNA in white blood cells, 2 piglets in 2 litters were derived from injected blastomeres, and 10 piglets in 3 litters were derived from recipient blastomeres. In the second experiment, inner cell mass cells of Day 6 Landrace embryos were injected into blastocoels of Day 6 Meishan embryos. Of 35 injected embryos transferred into 3 females, 2 overt chimeras of each sex were obtained in a single litter. In the overt male chimera, mtDNA clearly showed chimerism in spleen, pancreas, brain, kidney, lung, liver, heart, testis, and small intestine. The overt female chimera showed chimerism not only in blood but also in germ line according to a progeny test. No chimerism was detected in any of the 21 single-colored piglets in the second experiment.
