　　Transgenic baby marmosets in an image published with the study that appeared in the journal Nature

　　Scientists at Japan's Central Institute for Experimental Animals led the study that made the transgenic marmosets. The scientists say they injected a green glowing protein found in jellyfish into fertilized marmoset eggs. They chose this gene because it is easy to see with a florescent light.

　　Four of the five marmosets born as part of the experiment carried the foreign gene in several kinds of tissue. The fifth only carried the green protein in its placenta tissue at birth. Two of the animals later showed the foreign gene in their reproductive cells. This means they would pass on the gene for the green protein to their young.
