Fig. 5From: Anethole improves the developmental competence of porcine embryos by reducing oxidative stress via the sonic hedgehog signaling pathwayEffect of AN on the levels of proteins related to sonic hedgehog (SHH) signaling in porcine IVF embryos. Representative immunofluorescence images of A SHH, B PTCH1, C SMO, and D GLI1 in D2 embryos with and without AN treatment. Scale bar = 50 μm. E Relative fluorescence intensities of SHH, PTCH1, SMO, and GLI1 in D2 embryos with and without AN treatment (n = 30 per groups). F Relative expression levels of SHH signaling-related genes in D2 embryos with and without AN treatment (n = 3 per groups). Data are from three independent experiments, and different superscript letters indicate a significant difference (P < 0.05)Back to article page
