Similarly, GH1 (green) and nuclear (DAPI) fluorescence staining (Figures 2, 3) demonstrated that the mean fluorescence intensity of GH1 protein was significantly reduced in the placentas of the IUGR group (n = 5) compared to the AGA group (n = 5) (***p < 0.001) (Figure 8). Here, GH1 is linked to fetal growth restriction.
