The effect of pure synthetic Exodus on the cytokine-dependent human myeloid progenitor cell line MO7E.43 This cell line requires GM-CSF and SLF for maximal proliferation. The addition of Exodus almost completely inhibited proliferation. However, viability as assessed by trypan blue exclusion did not change with the addition of Exodus. Each data point is the mean of six separate experiments performed in triplicate. Stars denote statistical significance at P < .05 using a paired t-test between the Exodus-treated MO7e cells in GM-CSF/SLF and MO7e cells only in GM-CSF/SLF.
