ABSTRACT
<p><b>OBJECTIVE</b>To establish a rabbit tumor cell line and to characterize its biological parameters.</p><p><b>METHODS</b>VX2 tumor tissue was used for the primary culture in vitro. After 40 passages, the cell morphology, CK expression (immunohistochemical staining), cell cycle, karyotype and tumorigenecity in rabbits and nude mice were investigated.</p><p><b>RESULTS</b>The newly established cell line VX2 was maintained in continuous culture for over 70 passages in 10 months. Morphologically, VX2 cells were polygonal to short spindled. Tonal fibril and tight junction were found under the electron microscope. CK was positive. The cell cycle analysis showed 69.3% in G1 phase, 5.6% in G2 phase and 25.1% in S phase. The population doubling time was 34.5 hours. The chromosomal analysis showed a hypotriploidy with a median chromosome number of 58 approximately 62. The tumorigenecity in rabbits and nude mice were both 100%.</p><p><b>CONCLUSION</b>The established VX2 cell line derived from rabbit squamous carcinoma could serve as a model system for experimental oncology in the rabbit.</p>
