ITGAM and Miyoshi myopathy: ASC were positive for CD90, CD105, and CD73 (expression >97%), and negative for the hematopoietic markers CD45, CD14, HLA-DR, CD11b, and CD19 (expression <0.5%), without any detectable differences between cells from healthy donors or MM patients, in terms of either the percentage of positive cells or the mean fluorescence intensity (Table 1 and Figure 1C).
