(E-G) Generation of AP-like double-membrane compartment from the stacked Golgi. A quick-frozen replica (E) and a substituted thin section (F, G) are shown. Scale bars = 0.5 µm. The distal stacks are extended, curved, and form AP-like structure (E, F). Mitochondria are encircled by the Golgi membrane (F). (G) The AP-like structure was separated away from Golgi stacks.
