Fig. 5.
Surface antigen phenotype of the different cytokine-dependent EML cells.
Shown are FACS-generated histograms of Sca-1 and c-kit expression as well as Mac-1 (Cd11b) and Gr-1 expression in (A) EML cells, (B) EML cells treated overnight with IL-3, (C) EML/GM-CSF cells, and (D) EML/GM-CSF cells treated for 5 days with ATRA (10−5 M). The percent of cells in each quadrant is indicated.
