Platelet counts in newborn and adult mice. One-day-old healthy neonates had significantly lower platelet counts than healthy adult mice. Control mice received daily injections of the antibody vehicle and had platelet counts similar to those of untreated age-matched animals. Mice rendered thrombocytopenic by daily injections of MWReg30 had platelet counts that were significantly lower than age-matched placebo controls. Data are shown as means ± SE M. ∗∗ p < 0.001 vs. placebo control.
