Mouse Cell Division (IMAGE) Cold Spring Harbor Laboratory Caption A mouse cell is dividing abnormally in the center of this image. Instead of dividing its chromosomes equally into two cells, the cell is dividing into three cells. Chromosomes are stained in blue. These cells have a mutation in the gene dicer, which makes a protein that stabilizes chromosomes. Dicer makes sure the chromosomes divide and segregate evenly during cell division.
