Sentences with phrase «fetal cells the researchers»

Not exact matches

Fetal stem cells, which may turn out to be useful for treating conditions like Parkinson's, need to be cloned — that is, researchers need to take a cell from a body, put it in an embryo, and grow that embryo to a certain small size before harvesting the stem cells.
