Skin Deep: a breakthrough for Pluripotent stem cells

In 1998 James Thomson produced the world’s first human stem cell line, which is a single stem cell that is manipulated to divide into new stem cell clones producing a stem cell line. Whilst this opened up a whole new very promising area in genetic research it came under heavy criticism because it required embryonic stem cells. Embryonic stem cells come can only be harvested from a human embryo
