Monitoring Calcium Oscillations in Fertilized Mouse Eggs

Abstract : In mammalian species, including human, fertilization is characterized by the triggering of long-lasting calcium (Ca(2+)) oscillations in the egg cytoplasm. The monitoring of these Ca(2+) oscillations is a valuable technique to demonstrate that fertilization has occurred, to study egg activation events elicited downstream of the Ca(2+) signal, as well as to evaluate sperm quality. This chapter describes our protocol to monitor sperm-induced Ca(2+) oscillations in mouse eggs, using fluorescence microscopy techniques and the Fura-2-AM ratiometric Ca(2+) indicator.
