Unaltered receptor density in neonatal platelets. Characteristics of preterm neonates <32 weeks GA, 32 to 36 weeks GA, >36 weeks GA (t), infants 28d-2a, children 2 to 13a and adults >13a are displayed. (A) Forward- (FSC) and (B) side-scatter (SSC), (C) CD41a, (D) CD61, (E) CD42a, (F) CD42b, (G) CD49b, (H) CD49e, (I) CD49f, and (J) CD29 expression were assessed by flow cytometry in whole blood. All graphs show the median ± 95% confidence interval values. Differences were analyzed using the Kruskal-Wallis test. ∗P < .05; ∗∗P < .01; ∗∗∗P < .001. ns, nonsignificant.
