Cytoplasmic and mitochondrial ultrastructure in wild type and hyh MII oocytes. Representative electronmicrographs of MII oocytes cytoplasm from wild type and mutant homozygous (hyh) mice. Images show different cytoplasmatic structures as mitochondria, which are round or oval with or without vacuola (mt), the smooth endoplasmic reticulum (ser), which is mostly vesicular, and the extense fibrillar matrix of cytoplasmic lattice (cpl). Scale bar: 1 μm.
