Figure 5: Automated scanning and tracking of single cells: (A) Sequence of images of a single fluorescence-negative cell giving rise to two fluorescence-negative cells. (B) Sequence of images of a single fluorescence-positive cell dividing symmetrically into two fluorescencepositive cells. (C) Sequence of images of a single fluorescence-positive cell dividing asymmetrically into one fluorescence-negative cell and one fluorescence-positive cell.
