Long-term and non-invasive in vivo tracking of DiD dye-labeled human hepatic progenitors in chronic liver disease models

Figure 5 Detection of hepatic markers in transplanted mouse livers 80 d post-transplantation. A and B: Fluorescent microscopic images of mouse liver tissue cryosections that continue to show DiD signals 80 d post-transplantation and show co-expression of CK and c-Met only in the transplanted (TX-80 d) mouse livers, but not in the non-transplanted (No-TX) livers (scale bar = 50 μm); C and D: 63 × images showing the colocalization of CK and c-Met staining with DiD labeling, respectively (Scale bar = 50 μm and 10 μm). CK: cytokeratin; DAPI: 4',6-diamidino-2-phenylindole.
