Difference between portal vein injection and tail vein injection. (a) The fluorescent intensity of whole rats; the BMSCs were injected through tail vein; (b) the fluorescent intensity of dissected livers; the BMSCs were injected through tail vein; (c) the fluorescent intensity of whole rats; the BMSCs were injected through portal vein; (d) the fluorescent intensity of dissected livers; the BMSCs were injected through portal vein; (e) Dir-labeled BMSCs before injection were as positive control; (f) rats without cell injection were as negative control; (g) the fluorescent intensity value and fold changes of the dissected livers of two groups; the difference was statistically significant.
