In response to overnight whole-blood stimulation with lipopolysaccharide (LPS), healthy control (HC) significantly upregulated IFNƔ (p<0.01), IL-12 (p<0.01), MIP-1α (p<0.0001), TNFα (p<0.005), IP-10 (p<0.0001) while umbilical cord blood (UCB) had attenuated non-significant responses. IL-1β and IL-6 concentrations were significantly increased by both HC (p<0.005; p<0.01) and UCB (p<0.05; p<0.001). UCB had a significant increase in IL-10 (p<0.0001), while HC showed an attenuated non-significant increase. UCB also had a trend towards greater increase in MCP-1 post-LPS stimulation (p<0.0001) when compared to HC (p<0.01).
