Eggs of the amphibian, Xenopus laevis, were quick-frozen, deep-etched, and rotary-shadowed. The structure of the extracellular matrix surrounding these eggs, including the perivitelline space and the vitelline envelope (VE), was visualized in platinum replicas by electron microscopy. The perivitelline space contains an elaborate filamentous glycocalyx which connects microvillar tips to the plasma membrane, to adjacent microvilli, and to the overlying VE. The VE is comprised of two layers, the… CONTINUE READING
