Abstract:Seven human testicular tumors were transplanted into artificially immunosuppressed mice. Two of them grew progressively (TT2 and TT6) and a serially transplantable line was developed from TT2. The xenografts maintained only the embryonal carcinoma components of originally mixed (embryonal cell carcinoma and choriocarcinoma) donor tumor. Although the histology did not change remarkably with passages, the xenografts lost their capacity to express human choriogonadotropin and α-fetoprotein. The latency period sho… Show more
