Left column: Previous method for creating induced pluripotent stem cells (iPSCs); right column: iPSCs produced with the new method developed by Dr. Hanna. Top: Skin cells (red); center: iPSCs from skin cells (green); bottom: superimposed top and center images. Skin cells that have been reprogrammed into iPSCs appear light yellow. Only a small percentage of the cells on the left have been reprogrammed, in contrast with the high success rate seen with the new method on the right
