Except for the lack of expression of normal BCR in m-bcr cell lines and of ABL1a-BCR expression in all cell lines, no consistent correlation of expression or lack of expression of BCR and ABL or of ABL-BCR reciprocal fusion genes could be found with cell lineages and translocation types.     ///    An ABL-BCR transcript of the 1a splice variant was not detected in any of the cell lines.
