From: Induction and inhibition of oocyte maturation by EDCs in zebrafish
EDCs induce zebrafish oocyte maturation. The morphology of oocytes after three hours of each treatment was photographed. Left-side panels indicate oocytes in zebrafish Ringer's solution. In right-side panels, oocytes were fixed in clearing solution for observation of germinal vesicles. Oocytes remained opaque after EtOH treatment whereas they became transparent after 17α, 20β-DHP, DES, TAM or 4-OHT treatments. Germinal vesicles were seen near the center of oocytes after EtOH treatment whereas they disappeared after 17α, 20β-DHP, DES, TAM or 4-OHT treatments. The arrow indicates germinal vesicle.
