Ultrastructure appears affected by organelles arrested in the autophagic processing. a-c. High magnification electron microscopy images demonstrate various stages of autophagosome formation, type and size. d. Autophagic degradation of endoplasmic reticulum. e. The coexistence of free glycogen and membrane-encapsulated glycogen, possibly very large lysosome. f. Very high magnification of lysosome containing glycogen
