Figure 3.

Flow cytometric analysis of bone marrow cells from a cat with myelodysplastic syndrome with excess blasts. Flow cytometric histograms show the isotype control and cells with positive reactivity with some human monoclonal antibodies. Fifty-two percent of the cells are positive for cluster of differentiation (CD)18, whereas immunophenotyping with anti-CD33, anti-CD117 and anti-CD235a antibodies shows a weak reactivity. A significant degree of positive reaction to CD41 and CD61 is demonstrated. Blue line = CD markers; red line = isotype control
