Figure 5. IL-33 promoted the proliferation of HCECs via its receptor ST2.

A, B: Cell proliferation of HCECs treated with or without recombinant IL-33 protein (5 and 10 ng/mL) and soluble ST2 protein (10 ng/mL) for 48 and 72h was measured by CCK8 assay; C, D: Cell viability of HCECs treated with or without recombinant IL-33 protein and soluble ST2 protein for 48 and 72h was examined by cell count. ^aP<0.01; ^bP<0.001.
