Short excerpt from a YouTube video by Joy Kong, MD contrasting embryonic stem cells and umbilical cord (placental) stem cells. The speaker states embryonic stem cells originate from a forming embryo around day 5–7 after fertilization, while umbilical cord stem cells are obtained at a live, healthy birth when the cord (and placenta) is typically cut and discarded but can instead be sent to tissue banks.

Around day five to seven after fertilization.

There seems to be a lot of confusion between embryonic stem cells and umbilical cord stem cells. They're completely different things. The embryonic stem cells come from a forming embryo, usually day five to seven after fertilization. Whereas the umbilical cord stem cells come from a life healthy birth. When the baby is born, the cord is cut, usually the cord and the placenta is tossed away into biological waste basket. But now we can send them to tissue banks to get some powerful cells out of there.
