I would encourage anyone to be highly skeptical of terms such as "fetal tissue," especially when discussing stem cells. "Fetal tissue" in this case means umbilical cord and placenta. However, aborting a fetus to harvest such material would be contraindicated in the use of stem cells, because LIVE cells are required for regenerative injections. As you might know, aborted fetuses are first chopped for retrieval through a suction tube...which not only would kill cells present, but mixes them together in a homologous solution...useless for this purpose. Stem cells are only present in harvestable quantities in certain parts of the body.

This article discusses other fetal tissues used for other medical research, but, again, I encourage everyone to be skeptical about what information is garnered through MSM. This article discusses fetal tissue used for the development of the "polio vaccine," but that vaccine is/was a fraudulent hoax. It is now known that the disease called "polio" is/was a broad-spectrum neurological disorder associated with exposure to certain pesticides, most notably, DDT. https://www.cnn.com/2015/07/17/health/fetal-tissue-explainer/index.html
