Proliferation capacity of THP-1 cells treated with GL-PS after adding GM-CSF/IL-4. (A) Effect of adding GM-CSF/IL-4 to THP-1 after three-day treatment of GL-PS as determined by XTT proliferation assay. The results represented the mean ± SD of three representative experiments. *p < 0.05; ** p < 0.01; ***p < 0.001 versus that without GM-CSF/IL-4 added. (B) Trypan blue exclusion assay. THP-1 cells after adding either GM-CSF/IL-4 or GL-PS were counted. The results represented the mean ± SD of three representative experiments. *p < 0.05; ** p < 0.01; ***p < 0.001 versus that of THP-1 cells.
