In vitro and clinical evaluation of platelet-rich plasma combined with angioplasty in diabetic foot treatment

Figure 1 Screening of the optimal concentration of platelet-rich plasma for promoting the proliferation of human umbilical vein endothelial cells, human dermal fibroblasts, and human immortalized keratinocytes. A: Viability of human umbilical vein endothelial cells; B: Viability of human dermal fibroblasts; C: Viability of human immortalized keratinocytes. Significant differences in experimental data were analyzed using conventional one-way analysis of variance. All assays were performed in triplicate. ^bP < 0.01 vs the control (CTRL) group; ^cP < 0.001 vs CTRL group. PRP: Platelet-rich plasma.
