National Taiwan University announced yesterday that three transgenic green fluorescent pigs were successfully produced and bred by the university's tissue engineering research team.
Wu Shinn-chih, assistant professor in the Institute and Department of Animal Science and Technology lauded this breakthrough as a significant milestone in the study of regenerative medicine.
Furthermore, the achievement makes Taiwan the top country in the world in transgenic technology, said Wu.
Wu said out because of genetic similarities, the study of pigs is very critical to stem cell and cloning research for humans.
By injected a green fluorescent protein into embryonic pigs, researchers can trace the development of the tissues during the physical development of the pigs.
Moreover, by injecting the green protein during the early stages, Wu said, even the bone marrow, blood, and tissues of the animal can manifest the green color.
The findings can also be instrumental in furthering the study of regenerative medicine for humans to repair damage in body parts such as cartilage, teeth, skin, and ligaments, Wu added.
"Unlike the green pigs in other countries which only manifest the color in some parts such as the snout or feet, our pigs show a green fluorescence throughout their lifespan and all over their bodies," said Wu.
NTU Principal Dr. Lee Si-chen (李嗣涔) said NTU is equipped with state-of-the-art laboratories for genetic research studies. The school is also in collaboration with experts from the medical, veterinary, and biomedical engineering fields to facilitate future studies of stem cell research in Taiwan.
