==Chorionic villi and stem cells==
Recent studies have discovered that chorionic villi can be a rich source of fetal stem cells, multipotent [[mesenchymal stem cells]].<ref name="wash_post">{{Cite news |last=Weiss |first=Rick |date=2007-01-08 |title=Scientists See Potential In Amniotic Stem Cells |url=https://www.washingtonpost.com/wp-dyn/content/article/2007/01/07/AR2007010700674.html |access-date=2010-04-23 |work=The Washington Post}}</ref><ref name="nature">{{Cite journal |last=De Coppi |first=Paolo |last2=Bartsch |first2=Georg |last3=Siddiqui |first3=M Minhaj |last4=Xu |first4=Tao |last5=Santos |first5=Cesar C |last6=Perin |first6=Laura |last7=Mostoslavsky |first7=Gustavo |last8=Serre |first8=Angéline C |last9=Snyder |first9=Evan Y |last10=Yoo |first10=James J |last11=Furth |first11=Mark E |last12=Soker |first12=Shay |last13=Atala |first13=Anthony |year=2007 |title=Isolation of amniotic stem cell lines with potential for therapy |journal=Nature Biotechnology |volume=25 |issue=1 |pages=100–6 |doi=10.1038/nbt1274 |pmid=17206138 |s2cid=6676167}}</ref><ref name="urlStem Cells - BiocellCenter">{{Cite web |title=Stem Cells – BiocellCenter |url=http://www.biocellcenter.com/en/services_research/stem_cells/ |url-status=dead |archive-url=https://web.archive.org/web/20100111035407/http://www.biocellcenter.com/en/services_research/stem_cells/ |archive-date=11 January 2010 |access-date=2010-01-11}}</ref>

A potential benefit of using fetal stem cells over those obtained from embryos is that they side-step [[stem cell controversy|ethical concerns]] among anti-abortion activists by obtaining pluripotent lines of undifferentiated cells without harm to a fetus or destruction of an embryo. These stem cells would also, if used to treat the same individual they came from, sidestep the donor/recipient issue which has so far stymied all attempts to use donor-derived stem cells in therapies.{{citation needed|date=August 2015}}

Artificial heart valves, working tracheas, as well as muscle, fat, bone, heart, neural and liver cells have all been engineered through use of fetal stem cells.<ref name="urlStem cells scientific updates - BiocellCenter">{{Cite web |title=Stem cells scientific updates – BiocellCenter |url=http://www.biocellcenter.com/en/services_research/scientific_updates/ |url-status=dead |archive-url=https://web.archive.org/web/20100111035235/http://www.biocellcenter.com/en/services_research/scientific_updates/ |archive-date=11 January 2010 |access-date=2010-01-11}}</ref>
