iPS BACKGROUND. “Traditionally, scientists have worked with both embryonic and adult stem cells as research tools … Although some adult stem cells do have differentiation capacity, it is often limited in nature, which creates narrow options for use. Thus, induced pluripotent stem cells represent a promising combination of adult and embryonic stem cell characteristics.”
