Surface morphology of leukemic cells from chronic myeloid leukemia under atomic force microscopy.
Atomic force microscopy (AFM) represents an important instrument for measuring mechanical properties of biological materials ranging from single molecules to normal or malignant cells. AFM provides a 3D profile of the surface on a nanoscale, by measuring forces between a sharp probe (<10 nm), supported on a flexible cantilever, and surface at very short distance (0.2-10 nm probe-sample separation). The AFM tip "gently" touches the surface and records the small force between the probe and the surface. The patients were three normal human subjects and nine patients with chronic myeloid leukemia in different phases of disease. With atomic force microscope, numerous spicules were observed on the surface of leukemic cells, especially in blastic phase of CML.
