Pluripotent stem cells are isolated from human embryos that are a few days old. Cells from these embryos can be used to create pluripotent stem cell "lines" —cell cultures that can be grown indefinitely in the laboratory. Pluripotent stem cell lines have also been developed from fetal tissue obtained from fetal tissue (older than 8 weeks of development).

You can find stem cells in the umbelical cord of a baby or in the embryo itself.

In the first ten days after fertilization, they can be found in the embryo of all humans. They are also found in adults in the bone marrow and brain stem.
