Glyphosate exposure affects porcine oocyte maturation. A Representative morphology of oocytes maturation after 400 μmol/L glyphosate exposure. a: porcine oocytes with polar body. b: porcine oocytes without polar body. Arrow indicated PBI. Bar = 100 μm, Enlarge: Bar = 30 μm. B Rate of polar body extrusion in control and different concentrations of the glyphosate-exposed groups (100, 200 and 400 μmol/L). Different letters, significant difference (P < 0.05). C Representative images of COCs with 3 deferent expansion degrees. Bar = 100 μm. Glyphosate: 400 μmol/L. D Relative expansion of cumulus was analyzed in the control and 400 μmol/L glyphosate groups. Grade A: complete expansion; Grade B: partial expansion; Grade C: poor expansion. **, P < 0.01. Glyphosate: 400 μmol/L. E Expression of cumulus expansion-related genes was detected in control and 400 μmol/L glyphosate groups. *, P < 0.05
