[Electron microscopic studies of the endoplasmic reticulum in whole--mount cultured human nasopharyngeal carcinoma cell line].
The endoplasmic reticulum system (ER) in whole-mount human nasopharyngeal carcinoma parent cell line (CNE-2Z) and its variants L2, H2, L4 was observed using potassium permangnate as a fixtive. In lamellapodia and labopodia, the ER was arranged as a nest structure, but it usually formed lines of straight tubules in the filopodia. The results suggested that there may be some relationship between the ER and the functional activities of pseudopodia. No significant difference of ER was found yet in morphology, structure, quantities and distribution between CNE-2Z cells and its variants.
