therapeutic cloning (thěr'ə-py 'tĭk) Pronunciation Key
The production of embryonic stem cells for use in replacing or repairing damaged tissues or organs, achieved by transferring a diploid nucleus from a body cell into an egg whose nucleus has been removed. The stem cells are harvested from the blastocyst that develops from the egg, which, if implanted into a uterus, could produce a clone of the nucleus donor. |
| the offspring of a zebra and a donkey. |
| a screen or mat covered with a dark material for shielding a camera lens from excess light or glare. |
A type of cloning with the goal of harvesting embryonic stem cells from the resulting blastula to grow tissues and other biological products with therapeutic value. (See clone; compare reproductive cloning.)
