L21–6-positive CFU-C in normal BMC. Plastic dish-nonadherent LEW or BN BMC (5×104) were cultured in a fibrin clot culture system for 6 days and generated CFU-C that were exposed to mAb L21–6. (A) CFU-C in BN BMC were not stained with L21–6. (B) The positively stained dispersed-type CFU-C in LEW BMC were composed of macrophages and dendritic like cells (without counterstain) (Original magnification; × 100).
