GM-CSFR (CD116) expression on BM-MNCs in CMML vs control. (A) Dot plot of a representative CMML sample and healthy control stained with anti-CD116 and analyzed by multicolor flow cytometry. (B) Fifteen unique CMML samples and 5 healthy controls gated by myeloid subpopulation (CD 3+negative control) and stained with anti-CD116 measured by (C) the percent positive CD116 cells (D) and the mean fluorescent intensity of CD116. Significant P values are indicated using a paired Student t test.
