Fig 1 Differential CB CD34+ progenitor cell expression of TLR-2, TLR-4, and TLR-9 between high- and low-risk infants. CB mononuclear cells from high- and low-risk infants were stained with antibodies to surface TLR-2 and TLR-4 and intracellular TLR-9. CD34+ progenitor cells were gated and analyzed for differences in TLR expression. Data are presented as geometric means (95% CIs), and significant findings are indicated on the graph.

Fig 2 Differential CB CD34+ progenitor cell expression of IL-3Rα, IL-5Rα, and GM-CSFRα between high- and low-risk infants. CB mononuclear cells from high- and low-risk infants were stained with antibodies to surface IL-3Rα, IL-5Rα, and GM-CSFRα. CD34+ progenitor cells were gated and analyzed for differences in hematopoietic cytokine receptor expression. Data are presented as geometric means (95% CIs), and significant findings are indicated on the graph.

Fig 3 Responses to hematopoietic cytokines (IL-3) with or without LPS costimulation of CB CD34+ progenitor cells in high- and low-risk infants. CB mononuclear cells from low- and high-risk infants were enriched for CD34+ cells and stimulated with the hematopoietic cytokine IL-3 (1 ng/mL) or IL-3 and LPS (10 μg/mL) for 14 days (5% CO2 in 37°C). Data are presented as means ± SEMs, and significant findings are indicated on the graph.

Fig 4 Responses to hematopoietic cytokine (IL-5) with or without LPS costimulation of CB CD34+ progenitor cells in high- and low-risk infants. CB mononuclear cells from low- and high-risk infants were enriched for CD34+ cells and stimulated with the hematopoietic cytokine IL-5 (1 ng/mL) or IL-5 and LPS (10 μg/mL) for 14 days (5% CO2 in 37°C). Data are presented as means ± SEMs, and significant findings are indicated on the graph.

Fig 5 Responses to hematopoietic cytokine (GM-CSF) with or without LPS costimulation of CB CD34+ progenitor cells in high- and low-risk infants. CB mononuclear cells from low- and high-risk infants were enriched for CD34+ cells and stimulated with the hematopoietic cytokine GM-CSF (10 ng/mL) or GM-CSF and LPS (10 μg/mL) for 14 days (5% CO2 in 37°C). Data are presented as means ± SEMs, and significant findings are indicated on the graph.
