Figure 1. Kisspeptin fibre density in the perinuclear zone of non‐pregnant and pregnant rats.

Figure 1

A, representative dual‐label confocal images showing kisspeptin immunoreactive fibres (red) and oxytocin immunoreactive neurones (green) in the supraoptic nucleus (SON) and perinuclear zone (PNZ) of a non‐pregnant rat (NP), an early‐pregnant rat (G7), a mid‐pregnant rat (G14) and a late‐pregnant rat (G21). Scale bars = 50 μm. B, relative kisspeptin fibre density within the supraoptic nucleus. One‐way ANOVA showed no significant effect of reproductive status (F 3,43 = 1.46, P = 0.24). C, relative kisspeptin fibre density within the perinuclear zone. One‐way ANOVA showed a significant effect of reproductive status (F 3,43 = 3.95, P = 0.01); ** P ≤ 0.01 compared to non‐pregnant rats, Bonferroni's post hoc test.
