title: Electron microscopy of glycogen in mouse cleaving embryos.
abstract: The blastomeres of mouse morulae contain an abundance of beta-glycogen particles detectable cytochemically with good specificity; these particles are dispersed in the hyaloplasm. Attention is drawn to the fact that, with conventional staining techniques, the glycogen of mouse cleaving embryos can easily be confused with ribosomes in the electron microscope.
