% Binucleated Myocytes.

<p>The proportion of cardiac myocytes that were binucleated in the left and right ventricle of untreated preterm (solid bar), preterm + GC (glucocorticoid exposed, dotted bar) and term (open bar) piglet hearts. Mean ± SEM. N = 12 for all groups. * <i>P</i><0.05 compared to untreated preterm group. ^#<i>P</i><0.05 compared to left ventricle within the same group (paired t-test). Significant differences indicated only where these existed independently of litter effects.
