viSNE (IMAGE) Columbia University Irving Medical Center Caption viSNE reveals the progression of cancer in a sample of cells taken from a patient with acute myeloid leukemia. In figure a, the contours represent cell density in each region of the map. Each point represents a cell from the diagnosis sample (top, purple) or relapse sample (bottom, red). In figure b, cells from both diagnosis and relapse samples are shown in each map. Cells are colored according to intensity of expression of the indicated cell markers, enabling the comparison of expression patterns before and after relapse. For example, Fit3 is expressed primarily in the diagnosis sample, while CD34 emerges in the relapse sample.
