However, this study for the first time provides direct evidences that MCP-1/CCR2 axis is at least partly responsible for the myocardial homing factor of MSCs in DCM and also indicates that new therapeutic options providing MCP-1 or CCR2 to the myocardium may become necessary for the treatment of DCM patients. The gene discussed is CCR2; the disease is familial dilated cardiomyopathy.
