There are two types of fetal stem cells:

# Fetal proper stem cells come from the tissue of the fetus proper and are generally obtained after an [[abortion]]. These stem cells are not immortal but have a high level of division and are multipotent.
# Extraembryonic fetal stem cells come from [[extraembryonic membrane]]s, and are generally not distinguished from adult stem cells. These stem cells are acquired after birth, they are not immortal but have a high level of cell division, and are pluripotent.<ref>{{cite book |last1=Moore |first1=Keith L. |last2=Persaud |first2=T.
