Human B-blast specific target determinants in CML: a methodological study.
A method for preparation of purified human PWM stimulated B lymphoblasts and their usefulness as targets in CML is described. The purified B lymphoblasts were found to carry surface membrane immunoglobulin (SmIg) and HLA-DR antigens and were non E-rosette forming. In contrast, PHA-stimulated lymphoblasts were found to be E-rosetting, SmIg negative and without serologically detectable HLA-DR antigens, and thus were characterized as T lymphoblasts. Using B and T lymphoblasts in parallel as targets in CML, it was possible to demonstrate target determinants exclusively expressed by the B lymphoblasts.
