Table 4 Lymphocyte proliferation in cord blood and maternal peripheral blood with and without CD25+ depletion

From: Characterization of regulatory T cells in urban newborns

   Proliferation Index (PI)*  
   CD25+ Undepleted CD25+ Depleted  
  N Median Range Median Range Wilcoxon
Cord blood 78 101.8 5.7–776.7 109.9 5.4–943.6 0.56
Maternal Peripheral blood 52 216.7 1.0–713.8 238.3 0.7–798.0 0.02
  1. * Proliferation index (PI) is calculated as ratio of mean counts per minute (cpm) of stimulated over mean cpm of unstimulated cell triplicates.
