Comparison of semiquantitative parameters of placental ultrastructures between GDM and control group. (a–c) The terminal villi of GDM (a) and control (b) placenta. (c) Placental barrier thickness (arrow) of GDM group (6746.15 ± 1270.22 nm, n = 10) was significantly thicker than that of control group (4591.34 ± 1178.60 nm, n = 10; P < 0.05). Bar = 5 um. (d–f) The terminal villi of GDM (d) and control (e) placenta. (f) The BM of ST in GDM group (1077.49 ± 194.39 nm nm, n = 10) was thicker than that in control group (707.54 ± 256.56 nm, n = 10; P < 0.05). Bar = 1 um. (g–i) The density of ST apical microvilli in GDM (g) and control (h) placenta. (i) The density of ST apical microvilli in GDM group (44.36 ± 21.95 per 10 um, n = 10) was significantly lower than that in control group (77.13 ± 20.82 per 10 um, n = 10; P < 0.05) and even microvilli-free in some areas. Bar = 2 um.
