We also observed that cell surface CD4(-)CD8(-)CD3(-) cells with rearranged TCR genes developed from Id3 -transduced but not from control-transduced pre-T cells in an FTOC .
 ( cell line: FTOC, None) , ( protein: Id3, None) , ( DNA: rearranged TCR genes, None) , ( cell type: pre-T cells, None) , ( cell line: Id3 -transduced, None) , ( cell type: cell surface CD4(-)CD8(-)CD3(-) cells, None) , ( cell line: control-transduced pre-T cells, None)
