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

Figure 4 Co-expression of hepatic markers in the transplanted livers 15 d post-transplantation. Confocal images of liver tissue cryosections of transplanted (TX-15 d) and non-transplanted (No-TX) mice showing expression of CK and c-Met colocalization with DiD-labeling only in the transplanted mice. The non-transplanted mouse livers were negative for CK, c-Met and DiD (Scale bar = 25 μm). A: CK: cytokeratin; B: c-Met; DAPI: 4',6-diamidino-2-phenylindole.
