Objective To establish an subcutaneous xenotransplanted tumor model of human ameloblastoma in nude mice. Methods Ameloblastoma cells were absorbed by primary culture, repeat attachment and pancreas proteolytic enzyme were both used to purify them. Then, the purified cells were implanted subcutaneously into the nude mice. The specimens were respectively investigated by microscope in different spots after implanting. Results Ameloblastoma cells can survive in all of the 8 nude mice. The xenograft can be found on 23 days after implanting. The rate of successful inocutation is 25%. The subcutaneously xenotransplanted tumor cells can be found with microscope in the inter - muscle tissues of nude mice. Conclusion The subcutaneously xenotransplanted tumor model of human ameloblastoma in nude mice was successfully established and it may benefit to further studies on this tumor.
