CXCL8 and Miyoshi myopathy: Finally, when BCSCs were compared to benign SCs, a 100 fold increase in IL-8 expression in the CD49f−CD24−(MM) and CD49f−CD24+(MP) populations, a 20 fold increase in CD49f+CD24−(PM) cells, and a broader range of expression in the CD49f+CD24+(PP) population (10−2-102) were observed (Figure 5H).
