Abstract:

Craniopharynigoma samples were collected from 36 patients. Out of the 36 samples, 29 achieved successful sub-culturing, with a success rate of 80.6%. Immunohistochemistry staining showed that cytokeratin-7 was positively expressed in the cytomembrane and cytoplasm of craniopharyngioma cells at 6-8 passages, confirming that all cultured cells were squamous epithelial cells. The doubling time of craniopharyngioma cells was 3 days, as confirmed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. In this study, craniopharyngioma cells cultured in vitro were established; however, establishment of immortalized craniopharyngioma cell lines requires further research.
