Numbers and density of ionized calcium-binding adapter molecule-1 (Iba-1)-stained cells at postnatal days (P)7 and 14 in rats raised in control (CL) and small (SL) litters. a–d CA1. e, f CA3. g, h Dentate gyrus (DG) hilus. i, j DG molecular region. k, l DG sub-granular (SG)/granular region. Data are mean + SEM. N = 6–12 per group. *p < 0.05. c, d Representative photomicrographs of the CA1 region from P14 rats illustrating differences in numbers and density of Iba-1-stained cells. Scale bars = 50 μm
