Neutrophil and macrophage infiltration into the mouse decidua during TL and PTL. Neutrophils were identified using anti-Neu7/4 antibody and macrophages were identified using anti-F4/80 antibody. NewCast software was used to quantify neutrophil and macrophage numbers relative to total cell numbers in the decidua during late gestation, term labour and post-partum (TL), LPS-induced PTL and post-partum (LPS PTL) and RU486-induced PTL and post-partum (RU PTL). Shown are non-labouring samples (GD15, LPS Sham or RU Vehicle, white bars), GD18 (doted bars), GD19 (term not in labour, checkered bars), term and preterm labouring samples (grey bars) or post-partum samples (black bars). Results were expressed as mean ± SEM (n = 4–6). Significant difference with GD15/RU486 Vehicle/Sham LPS is indicated by *P < 0.05 and **P < 0.01.
