PAI-1 and uPAR levels are elevated upon exposure to cmvIL-10 or hIL-10. a MDA-MB-231 cells were cultivated in the presence of 10 ng/ml purified recombinant cmvIL-10 or hIL-10. At the indicated time points, culture supernatants were collected and levels of PAI-1 measured by ELISA. b MDA cells were cultured as above and levels of uPAR in the supernatant were determined by ELISA. Error bars represent standard error among three replicates for each data point. *p < 0.05. These results are representative of three independent experiments
