Abstract:
Objective To establish a subcutaneous and orthotopic transplatation tumor model of human esophageal cancer in nude mice .Methods Fresh tissues of human esophageal cancer were collected and transplanted into subcutaneous places of nude mice .The successfully transplanted primary generation tumor was passed down three times .Then tumor were implanted into the subcutaneous and esophageal submucous tissues of nude mice .The formation rate ,morphology ,invasion and metastasis of tumor were observed .Results The tumor formation rate of subcutaneous transplatation model was 60% ,it was low grade squamous cell carcinoma without lymph node and distant organ metastasis .The tumor formation rate of orthotopic transplatation model was 80% , the morphological characteristics were consistent with human original tumor .Lymph node and organ metastasis could be found ex-tensive .Conclusion We preliminary established effective subcutaneous and orthotopic transplatation tumor model of human esopha-geal cancer in nude mice .It might be an available model for further research of esophageal cancer .
