Inner mitochondrial membrane potential (  m), cytoplasmic ATP content and free Ca2+ levels in metaphase II mouse oocytes

Abstract excerpt

BACKGROUND: The relative magnitude of the inner mitochondrial membrane potential (DeltaPsim) has been suggested to indicate the competence of mammalian gametes and early embryos. This study examined the response of cultured somatic cells and mouse oocytes to inhibitors and conditions that affect DeltaPsim or metabolism, or both, and measured treatment-specific changes in ATP and cytoplasmic free Ca(2+). METHODS:...
