Stem cells can also be gathered from neural, umbilical and amniotic fluids. The neural stem cells can be harvested from the brains of the recently deceased. Another source of stem cells can be found in umbilical cords, placentas and amniotic fluid. These cells can be gathered harmlessly from pregnant individuals with minimal invasiveness. They can then be stored cryogenically for later use. Finally, adult stem cells can be obtained from bone marrow. While this process is destructive to the individual’s bone marrow, it offers the benefit of full compatibility with that individual.
