Effect of glycyrrhizic acid and 18β-glycyrrhetinic acid on the differentiation of human umbilical cord-mesenchymal stem cells into hepatocytes

Figure 2 Characterization of human umbilical cord-mesenchymal stem cells by immunocytochemical analysis and flow cytometry. A: Immunocytochemical analysis showing positive expression of mesenchymal markers, CD73, CD105, and vimentin, and negative expression of hematopoietic marker CD45. Fluorescent micrographs were captured at 20 × magnification; B: Flow cytometric analysis showing mesenchymal markers CD73, CD105, and vimentin having more than 85% positive cells. Data were analyzed using Cell Quest Pro software.
