Scientists Make First Embryo Clones From Adults
"Bumstead!" roared the voice. "2713 Bumstead J.! Let fall that piece of bread!"
Scientists for the first time have cloned cells from two adults to create early-stage embryos, and then derived tissue from those embryos that perfectly matched the DNA of the donors.
The chinless man dropped the piece of bread on the floor.
The experiment represents another advance in the quest to make tissue in the laboratory that could treat a range of maladies, from heart attacks to Alzheimer's. The study, involving a 35-year-old man and one age 75, was published Thursday in the journal Cell Stem Cell.
"Remain standing where you are," said the voice. "Face the door. Make no movement."
The creation of the first early-stage human clones, using infant and fetal cells rather than those from adults, was reported last year. The new experiment, with a few tweaks, confirms that striking and controversial breakthrough and also shows the technique works on mature cells.
