Objective To discuss the applycation possibility of themicroscopic stripping technique used in the primary culture of human embryonicesophagus squamous epithelial cells, and of the methodds for the isolation, depuration and subculture of the esophagus epithelial cells in vitro. Methods The squamous epithelial cells wereobtained from the esophagus mucous membrane of the 20-week abortion fetus through the microscopic stripping technique, and were digested with trypsin. Then, the morphological, immunohistochemical observation and the growth curve of the isolated cells were studied. Results The isolated cells were spherical in the cell suspension and spherical-like or polygon-like after attachment to the culture flask.The squamous epithelial specialized cytokeratin staining was bly positive. And the morphological studies by the transmission electron microscopy indicated that the cultured cells were squamous epithelial cells. The squamous epithelial cells reached the peak level 3-4 days after the transfer of the culture. The absorbanceat 3 and 4 days was significantly higher than that at 1,2,5 and 6 days (P＜0.05). Conclusion A large mumber of squamous epithelial cells can be available with the microscopic stripping technique and the digestion method. Thecultured squamous epithelial cells can be proliferated quickly, and fit for the tissue engineering study.
