Figure 2. Comparison of EPO-R and Sp1 expression measured by flow cytometry in CD4⁺ lymphocytes before and after stimulation with anti-CD3 antibody.

Figures A and B present changes in the number of EPO-R molecules per cell and the expression of Sp1, respectively. Midpoints of figures present medians, boxes present the 25 and 75 percentile and whiskers outside visualize the minimum and maximum of all the data, *p<0.05, Friedman ANOVA and Post Hoc test, MFI – mean fluorescence intensity.
