Cloned kidney transplant in cattle (6/6/2002)
Researchers with Tissue Engineering at Children's Hospital Bostonwho transplanted cloned cattle cells
that formed working mini-kidneys say their experiment shows the potential of cloning replacement tissues and organs.
The team, led by Dr. Anthony Atala, used the same technique used to clone Dolly the Sheep. They removed the DNA-containing nucleus from a cow's egg
and replaced it with cells from another cow's ear. The result was that the cloned cell started to divide.
The cloned embryo was then implanted into a surrogate cow for six weeks and removed.
Heart, skeletal and kidney cells were removed from the embryo and were grown into tissues in the laboratory. The cloned cells were then implanted into the cow that donated the ear cells.
Most important The cattle's immune system showed no signs of rejection, an important acheivement.
