Animal acts and tumor formation, growth and metastasis in NOD-SCID mice were observed. Primary and metastatic tumors were studied pathohistologically by HE and immunohistochemical staining.Results: The latent periods of tumor growth were 12~19 days and the taken rate of tumor was 100%. 32 days later, 5 NOD-SCID mice were found with tumors that had metastasized to areas mainly located in the abdominal cavity and the side of the kidney; the metastatic time of tumors in the mice also differed. The tumor cells of the primary nodules and the metastasis were similar with human retinoblastoma cells and positive in immunohistochemical staining of NSE.Conclusion: The subcutaneous model of retinoblastoma in NOD-SCID mice showed a high taken rate and a short latent period of tumor, which had a high metastatic rate and was the best model in research of behaviors of retinoblastoma at present.展开更多
