Cloning used to create glow in the dark dogs
Share This Article:
Scientists in South Korea have used cloning to create four beagles who glow fluorescent green under ultraviolet light. They are given an antibiotic makes their nails, skin, eyes and abdomen glow in the dark. The project has been designed to achieve the transplantation of a gene with a particular trait. The glowing effect visibly proves that this can be done. This means that it should be possible to insert genes related to human diseases into the cloned dogs, enabling research into the affects and cures for genetic conditions such as Parkinson’s disease. To create the effect the scientists injected canine fibroblast cells with a virus; this process inserted the fluorescent gene into a cells’ nucleus. This nucleus was put into an egg cell from another dog with its nucleus removed. The cloned embryo was then implanted into a surrogate mother. The puppies arrived in December 2007 but the project has only just been publicized. Lee Byeong-chun, a professor at Seoul National University is claimed to have been an assistant to Hwang Woo-suk, a stem cell researcher found to have faked data in the past. However, after years of review and confirmation of the findings this later work has been independently verified.
