1: a blob of cells which, as it differentiates, forms a parasitic relationship with a host body, often referred to as the 'mother' (the fetus takes nutrients from the mother and returns nothing, thus the term 'parasite'). The parasitism often lasts well after the pregnancy, during which the fetus resides within the body of the mother; in some species the post-birth parasitism lasts 18 years or more. Not to be confused with a human being, which is what a fetus is called only after being pushed through the birth canal of another human being.
2: A good source of stem cells, which are cells that have yet to differentiate into a specific type of cell. For some reason, stem cell research is a very controversial issue.
Note: In some human cultures, especially those with screwed up priorities, feti have more rights than the human women in which they germinate.
Stem cells from a fetus can help the disabled by regenerating into needed cells in damaged parts of their bodies.
