TTR and Cirrhosis: Furthermore, the GFP fluorescence of the grafted DPSCs colocalized with the immunofluorescence of the single-layer epithelial marker CK18 as well as the hepatocyte-synthesized plasma proteins albumin and TTR, which suggested that the grafted DPSCs with hepatogenic potency confirmed in vitro (Figs S1 and 3J–L), had differentiated into hepatocyte-like cells in host liver tissue with cirrhosis pathology.
