The zona pellucida (zona) is a glycoprotein coat that envelopes the oocyte and embryo,
binds sperm during fertilization and facilitates transfer of the embryo through the Fallopian …

OBJECTIVE: To characterize the architecture of the zona pellucida in living human eggs and
embryos, noninvasively with the PolScope, a digital polarizing light microscope. DESIGN …

The fine structure of the zona pellucida of mouse unfertilized egg cells and of mouse
embryos was investigated. In addition to standard fixation for electron microscopy, fixation …

The surface of the mouse and hamster zona pellucida and oocyte were examined with the
scanning electron microscope. Both zonae and ova were studied before fertilization, at the …

The zona pellucida is an acellular coat which surrounds the plasma membrane of fully
grown mammalian oocytes and which performs a variety of important functions during …

The distribution of the sperm-, lectin-and antibody-binding components was examined on
isolated fragments of the hamster zona pellucida. In all three studies, binding was much …

The zona pellucida is the acellular transparent envelope surrounding the mammalian
oocyte. An analysis of the changes in the structures of zona pellucida proteins is essential …

During the course of oocyte development and follicular growth an amorphous material is
deposited in the space between the oocyte and the surrounding granulosa cells. This …

This paper describes the ultrastructural appearance of guinea pig blastocysts that are in the
process of shedding the zona pellucida, and it attempts to relate these observations to …
