Flow cytometry. Representative histogram plots for the endothelial markers CD146 (A) and CD34 (C) are depicted on the left side showing the specific staining (continuous line) and the isotypic controls (broken line). Histograms are depicted for HCC and LCC derived from the standard or modified protocol as indicated in the graph. Bar charts depict mean values of CD146-positive (B) and CD34-positive (D) cells for the individual groups determined as mean values of at least n = 3 donors. **p ≤ 0.03.
