Fig. 3From: A novel approach to label bone marrow-derived mesenchymal stem cells with mixed-surface PAMAM dendrimersBM-MSCs retain their stemness following D-FITC uptake. BM-MSCs labeled with Hoechst (blue) and D-FITC (green, arrow) expressed Sca-1 in the cytoplasm, a cell marker specific to mouse BM-MSCs (brown), which shows that the stemness of the MSCs is retained after dendrimer uptake.
