Acetylcholinesterase (AChE) activity was determined in normal and malignant human cell lines by histochemical methods. In normal human fibroblasts, no AChE activity could be demonstrated by any histochemical technique or substrate. Enzymic activity was observed in
HT-1080
human fibrosarcoma cells, RD 2 human rhabdomyosarcoma cells, and SW 311 human colon carcinoma cells. Activity was localized around the nuclear envelope, in the cytoplasm and associated with the cortical region of most cells. The specificity of the reaction was shown through the use of specific
cholinesterase
inhibitors.

A modified histochemical procedure was used to detect specific acetylcholinesterase localization in cultured human cells. Enzymic activity was found in cytoplasm in the perinuclear zone and in the plasma membrane of 20% to 40% of
HT-1080
human fibrosarcoma cells. The presence of
pseudocholinesterase
was excluded using specific substrates and inhibitors.
