Lung metastasis and subcutaneous tumour models. (A) Subcutaneous tumour model. At day 0, 106 TSA-pGL3 cells/200 μL were SC injected (n = 15). At day 7, bioluminescence imaging was performed for the three homogeneous groups. The control group was IV injected with 200 μL of PBS, the hMSCs SC group was peritumourally injected with 5 × 105 cells/200 μL PBS and the hMSCs IV group was IV injected with 5 × 105 cells/200 μL PBS. At day 14, bioluminescence and three-dimensional fluorescence imaging were performed. The mice were euthanized, their Hb contents were measured, and the tumours were frozen for immunohistological studies. (B) Lung metastasis model. At day 0, 105 TSA-pGL3/200 μL PBS cells were IV injected (n = 8). At day 4, 200 μL of PBS (control) or hMSCs (5 × 105 cells/200 μL PBS) were IV injected. At day 10, bioluminescence and three-dimensional fluorescence imaging were performed. The mice were euthanized, and their Hb contents were measured. Hb, haemoglobin; hMSC, human mesenchymal stem cell; IV, intravenous; PBS, phosphate-buffered saline; SC, subcutaneous; SD, standard deviation; TSA-pGL3, TS/A-pc mouse adenocarcinoma cell line stably transfected with the luciferase reporter gene.
