Fig. 2From: Transferrin and antioxidants partly prevented mouse oocyte oxidative damage induced by exposure of cumulus-oocyte complexes to endometrioma fluidEffects of endometrioma fluid on spindle and chromosome of mouse oocytes. COCs were denuded and stained for mitochondrial function. a, d Green fluorescence indicates spindle. b, e Red fluorescence indicates chromosome. a, b Normal chromosomes and spindles shows barrel-shaped structure with slightly pointed poles formed by organized microtubules with chromosomes arranged on a compact plate at the equator. d, e Abnormal chromosomes and spindles shows a reduction in the longitudinal dimension of the spindle and chromosomes displaced by the plane of the metaphase plate, which is shown by the arrowBack to article page
