Karyotype analysis of teratocarcinomas and embryoid bodies of C3H mice.
Karotype and capacity for differentiation were determined in four transplantable teratomas, and their embryoid bodies, derived from C3H mouse embryos. An apparently normal karyotype was retained by one tumour and one subline that were able to differentiate into a wide range of tissues, but some chromosomal alterations were found in the two tumours and one subline that showed almost identical restrictions in their capacity for differentiation. Trisomy for chromosome 11 was shared by all three restricted tumours; two of the tumours had similar length changes in the same two chromosome (1 and 14) while the third was generally trisomic for four other chromosomes.
