Correlation between Therapeutic Efficacy of CD34+ Cell Treatment and Directed In Vivo Angiogenesis in Patients with End-Stage Diffuse Coronary Artery Disease

Figure 1

Protocol of follow-up, grouping, and analysis in the present study. Patients with severe coronary artery disease (CAD) having received CD34+ cell treatment with complete follow-up, divided into three groups based on different angiographic grades. Application of directed in vivo angiogenesis assay (DIVAA) further delineating the correlation between angiographic grading and endothelial progenitor cell- (EPC-) mediated regenerative potential.
