      This cell dataset contains cell boundaries of mouse osteosarcoma
      (bone cancer) cells. The dlm8 cell line is derived from dunn and is more
      aggressive as a cancer. The cells have been treated with one of three
      treatments : control (no treatment), jasp (jasplakinolide)
      and cytd (cytochalasin D). These are drugs which perturb the cytoskelet
      of the cells.
