Indeed, the internal and external architecture of cryoprocessed ameloblasts in transmission electron microscope preparations does not differ significantly from that of the conventionally prepared tissues (Nanci, Kogaya and Kawaguchi, manuscript in preparation).

In a recent morphological study of cryoprocessed human skin prepared using high pressure freezing and freeze substitution, KHGs were completely absent, even though abundant profilaggrin immunoreactivity was detected in the upper living layers and in cornified cells under the same fixation conditions (45).
