Stem cells are the body's master cells, the rare material from which we are built. Unlike normal body cells, they can reproduce an indefinite number of times and, when manipulated in the right way, can turn themselves into any sort of cell in the body. The most versatile stem cells are those found in the embryo at just a few days old. This ball of a few dozen stem cells eventually goes on to form everything that makes up a human . In 1998, James Thompson pronounced that he had isolated human embryonic stem cells in the laboratory. At last, these powerful cells were within the grip of scientists to experiment with, understand, and develop into fixes for the things that go wrong.
