New explanation for infertility: eggs lacking a mysterious ‘lattice’ ( www.nature.com )
Cytoplasmic lattices (bundles of fibres floating in the cytoplasm) in mammalian egg cells seem to be storage sites for many proteins that are essential for the development of the early embryo. The discovery indicates that their absence, which can be determined by genetic testing, would point towards infertility of the eggs.
