CCL2 and hydrops fetalis: Of interest, within the cytokines/chemokines analyzed in HF patients, the levels of IL-12p70, IL-8, MCP-1, MIP-1α, and VEGF correlated (P < 0.05) positively with the endothelial proliferation index assessed in two distinct time points (36 and 48 hours), with IL-8 and VEGF showing a higher correlation (Figure 4(b)).
