What are foetal stem cells?
Foetal stem cells are isolated from foetuses aborted during early pregnancy. Many different types of tissue-specific stem cells can be isolated from foetal tissue including some tissue stem cells which cannot be found in the adult, such as nerve stem cells. Stem cells very similar to embryonic stem cells, called embryonic germ cells, have also been collected from foetal mouse tissue, though the ability to establish equivalent human cell lines has not been proven.
