CD24 and Miyoshi myopathy: Moreover, triple staining with NCAM revealed that CD24 is expressed in low levels only in putative MM fractions; CD24+NCAM+EpCAM− and CD24+NCAM−EpCAM− cell fractions (2.0±1.2%, 3.7±2.8% of total cells, respectively) in contrast to a CD24+NCAM−EpCAM+ differentiated phenotype (34.1±14.6% of total cells) (Fig. 4b).
