Figure 7From: Sdf-1 (CXCL12) induces CD9 expression in stem cells engaged in muscle regeneration Myogenic potential of stem cells is not sufficient to apply them in damaged skeletal muscle therapy. Induction of CD9 expression in a Sdf-1 CXCR4-dependent way leads to increased ability of stem cell lines to migrate and fuse with myoblasts. CXCR, CXC chemokine receptor.Back to article page
