FIG. 5.

ICs and hMSC localization in the portal vein of the liver. Before transplantation, ICs and hMSCs were labeled with PKH26 (red) and PKH67 (green), respectively. The livers were harvested 7 days after transplantation. Arrows indicate the ICs localized with hMSCs in the liver. Blue indicates nuclei stained with DAPI. Scale bars=50 μm. The percentages of both PKH67-positive (hMSC) and PKH26-positive (IC) clusters were evaluated from total clusters found in each liver (lower panel). *p<0.05 compared with HSs (10:1) group.
