In 1998, James Thomson of the University of Wisconsin-Madison derived the first human embryonic stem cell line. According to the National Institutes of Health, stem cells are “cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.” Stem cells are generally classified as either embryonic stem cells (ESC) or adult stem cells. Because of the unique nature of stem cells (as compared to other somatic cells), they have become of enormous importance in medical research, particularly as potential cures for life threatening diseases.
