  • Title: [Experimental teratomas from xenogenic embryonic implants in the urodele amphibian, Pleurodeles waltlii Michah].
    Author: Houillon C.
    Journal: C R Acad Sci III; 1989; 308(9):229-36. PubMed ID: 2499409.
    Abstract:
    Ambystoma mexicanum embryos in stages 5 to 32 were implanted into the coelomic cavity of larvae or metamorphosing larvae of Pleurodeles waltlii. Out of 76 experimental animals, 43 presented teratomas a few months later. In another series of experiments, Ambystoma embryos together with Pleurodeles embryos were implanted in 18 Pleurodeles larvae. Teratomas developed in 13 cases. Considering the two series, tumors evolved slowly and remained benign in 31 animals, whereas in 25 others, the tumor growth was faster and uncontrolled. Histological examination of these destabilized tumors indicates they are certainly xenogenic teratocarcinomas.
