Figure 1 Flow cytometry analyses of patient bronchoalveolar lavage and bone marrow. A: Bronchoalveolar lavage fluid samples were analyzed via flow cytometry, revealed an increased proportion of monocytes (12.4%, purple), CD33+ CD14+ CD300e+ mature monocytes accounted for approximately 4% of nucleated cells, and CD33+ CD14- CD300e+ partially immature monocyte accounted for 8.4% of nucleated cells; B: Flow cytometry studies of bone marrow samples revealed an increased proportion of monocytes (purple) that accounted for 44% of nucleated cells, and CD33^bright CD14- CD300e+ immature monocytes accounted for approximately 7.4% of nucleated cells.
