Fig. 2.
The distribution and morphology of mitochondria in immature oocytes at the GV stage, and 3 h after release from IBMX at which point GV breakdown (GVBD) had occurred. In the top row, mitochondria with an intact GV were labelled with mitotracker orange and mito-GFP. In the bottom row an oocyte was similarly treated after GV breakdown (GVBD). The merged images show that, in both types of oocytes, the mitotracker staining pattern matches that labelled with mito-GFP.
