Cell surfaces and embryos: expression of the F9 teratocarcinoma antigen in T-region lethal, other lethal, and normal pre-implantation mouse embryos.


F9 teratocarcinoma antigen is expressed normally on embryos which are homozygous recessive for each of 4 mutations lethal in early development, including t12. Homozygosity for two post-implantation T-region developmental lethal genes, tw5 and T0r1, may alter F9 antigen expression but the results were not definitive. In addition, the time of appearance of… (More)
