(A) Representative photographs of mouse oocytes were obtained from confocal microscopy, (a, b, c, d, e and f) illustrate the different types of mitochondrial distribution: (a and b) homogeneous mitochondrial distribution throughout the entire oocyte; (c and d) heterogeneous-mitochondria distributed heterogeneously with aggregation, large granules distributed throughout the ooplasm; (e and f) peripheral mitochondrial in the periphery or central ooplasm of the oocyte. Original magnification 400×, white bars represents 20 µm. Staining by MitoTracker@Red FM. (B) Percentages of three mitochondria distribution types of the oocytes retrieved from the young and aged mice in different interventional groups.
