The developmental potential of various teratocarcinomas of different origins was examined by making chimeras with mouse embryos. Of 7 teratocarcinoma lines examined, only 2 were found to contain stem cells having the ability to form live-born chimeras; one was experimentally induced OTTBALB-2 and the other was spontaneously occurring STT-3. The latter showed remarkable ability to colonize mid-gestational fetuses and adults. This result not only demonstrates that EC cells of male primordial germ cells have the ability to form viable chimeras but also suggest that this kind of tumor is a useful source of EC cells to make chimeras. The advantage of using pluripotent cell lines such as EC cells or embryonic stem (ES) cells as a vector for introducing foreign genes into mouse embryos was discussed in relation to the study on gene function and on gene regulation during development.

D002471	Cell Transformation, Neoplastic	Cell changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm, and other attributes conferring the ability to invade, metastasize, and kill.

D002678	Chimera	An individual that contains cell populations derived from different zygotes.	Hybrids,Chimeras,Hybrid
D005822	Genetic Vectors	DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013724	Teratoma	A true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs. It is composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They are classified histologically as mature (benign) or immature (malignant).

D014162	Transfection	The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES.	Transfections
D014407	Tumor Cells, Cultured	Cells grown in vitro from neoplastic tissue. If they can be established as a TUMOR CELL LINE, they can be propagated in cell culture indefinitely.
