Study Design:
An experimental study to investigate the characterization of 3 chordoma cell lines.
Objective:
To characterize chordoma cell lines and generate hypothesis for further chordoma studies.
Summary Of Background Data:
Three cultured human chordoma cell lines have been successfully generated; however, their characterization is incomplete. Complete characterization of chordoma cell lines is necessary for these reagents to be a useful preclinical model.
Methods:
Three chordoma cell lines, CH 8, U-CH1, and GP 60, were cultured in different commercially available tissue culture media. They were also cultured in different environments, which included collagen substrate, various concentrations of glucose, and various levels of hypoxic conditions. The rate of cell proliferation was assessed by either MTT or numeration assay. A 3-dimensional (3D) cell culture model of these chordoma cell lines was also studied, and the expression of vimentin and cytokeratin was measured by immunofluorescence and Western blot. Additionally, the sensitivity of the 3 chordoma cell lines to 6 chemotherapeutic drugs was analyzed.
Results:
CH 8, GP 60, and U-CH1 cells proliferate more actively in Iscove Modified Dulbecco Medium or Dulbecco modified Eagle Medium and less actively in RPMI medium. All 3 chordoma cell lines universally grow better in collagen substrate and survive in hypoxic conditions, whereas glucose concentration has no significant influence on their growth properties. Chordoma cell lines grew well in 3D culture systems and formed acini-like spheroids and retained the expression of vimentin and cytokeratin. MTT analysis indicates that all 3 chordoma cell lines are sensitive to doxorubicin, yondelis, zalypsis, and cisplatin.
Conclusion:
We characterized 3 chordoma cell lines for differential growth properties in a variety of media and response to chemotherapeutic agents.
