Electron Micrographs of a Crystalline Lattice Structure in Yolk Platelets of the Amphibian Embryo

YOLK platelets are one of the cytoplasmic inclusions characteristic of embryonic cells, and constitute the most important reserve material for these cells. A weak birefringence has been reported from fresh or fixed yolk platelets of various amphibian embryos 1 . However, no further information is av...

Description
Summary:YOLK platelets are one of the cytoplasmic inclusions characteristic of embryonic cells, and constitute the most important reserve material for these cells. A weak birefringence has been reported from fresh or fixed yolk platelets of various amphibian embryos 1 . However, no further information is available concerning the physical organization of these inclusions. In the course of our electron microscopic studies of embryonic cells, regular fringe systems have been found over the whole area of yolk platelets, indicating a crystalline structure of the yolk matrix.
