[Ca2+]i and mitochondrial membrane potential of wildtype activated oocytes. a Cytoplasmic calcium concentrations ([Ca2+]i) showing dynamic changes in wildtype oocytes during activation. b Oocyte mitochondrial membrane potential of wildtype oocytes during activation. c Membrane potential fluorescence intensity during oocyte activation. The green and red curves represent labeling with JC-1, indicating relative fluorescence intensities of low membrane potential (488 nm excitation, 525 nm emission) and high membrane potential (561 excitation, 590 emission), respectively. d The black curve shows the ratio of high membrane potential to low membrane potential indicating relative mitochondrial membrane potential. e Living cell observation of Ctrl oocyte spindle formation f Living cell observation of subcortical F-actin distribution in Ctrl oocyte
