Dr. Valery Krizhanovsky wants to know what happens to our cells when they age

Pre-leukemic stem cells (top) with both mutated and healthy copies of the RUNX1 gene already display some of the characteristics of acute myeloid leukemia (AML). When the non-mutated copy of the gene is inactivated, disruptions in the spindle-assembly-checkpoint phase of cell division trigger cell death

Weizmann Institute researchers discover that a “standoff” between a mutated gene and its normal counterpart keeps certain cancer cells alive

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
