The in vivo imaging and tissue distribution of tumor-bearing mice. a In vivo images of 4T1 tumor-bearing mice administrated of free DiR or CTP/CDDP/DiR for 3 h, 6 h, 12 h and 24 h via tail vein injection. b Ex vivo images of organs and tumors excised from 4T1 xenograft tumor-bearing nude mice at 12 h after intravenous injection of TD/CDDP/DiR, TP/CDDP/DiR and CTP/CDDP/DiR. c Semiquantitative mean fluorescence intensity results of organs and tumors. Data are expressed as mean ± SD (n = 3)
