(C) IF stain showed that 9B2 antigens (red) were expressed at the junction between adjacent hepatocytes. F-actin (green) and DAPI (blue). (DOC)Figure S3 The 6-month teratoma observation study. The iPS cells were labeled with GFP (iPSC-GFP) then injected into mice in our experimental system (N = 4). The total follow up time was 6 months. The iPSC-GFP positive signals were examined by the Ex vivo GFP imaging. The 
results demonstrated that 22948146 there were no GFP signal could be found by Ex vivo GFP imaging. In addition, no tumor detected by histological when detail survey were performed in multiple organs including liver, lung, stomach, intestine, colon, kidney, bladder, and brain. (DOC) Figure S4 Interferons (IFN) and TNF-a are not inducers of IP-10. (A) In the injured liver, the expression of IFN-c and IFN-a mRNA were reduced and remained low despite iPS infusion. There was no significant difference in IFN-l. (B) Hepatic TNF-a increased after injury but was reduced by iPS infusion. The TNF-a receptor type 1 (TNF-a R1) expression increased significantly after injury. IPS infusion did not alter the expression levels of TNF-a R1 mRNA (n = 6, *p,0.05 vs. normal control, # P,0.05, vs. CCl4) (DOC) Supplementary Methods and Results Spurchase Thiazole Orange cytokine Array and IP-10 ELISAThe liver tissues of the CCl4-injured mice without or with iPS treatment were homogenized and prepared in PBS with protease inhibitors (10 mg/mL Aprotinin, 10 mg/mL Leupeptin, and 10 mg/mL Pepstatin) and 1 Triton X-100. The tissue lysates were centrifuged at 10,000 g for 5 minutes to remove cell debris. The protein TA-02 concentrations were quantified (DC-Bradford protein assay, Bradford, Bio-Rad, Hercules, CA, USA) and 200 mg of proteins were used for the analysis of cytokines by the commercialized assay kits (Mouse cytokine array panel A and IP-10 Immunoassay, R D, MN) according the manufacture’s instruction. The expression of individual cytokines in injured liver received iPS treatment was quantified by densitometry and expressed as fold change relative to their expressions in the injured liver without iPS treatment.Statistical AnalysisThe results were expressed as mean6SEM. Statistical analysis was performed by using an independent Student t test and oneand two-way ANOVA with Tukey post hoc test when appropriate. The survival analysis was performed by using logrank test. A p value ,0.05 was considered statistically significant.(DOC)Table S1 Primer sequences used in real time-PCR.Supporting InformationFigure S(DOC)Table S2 Organ distribution of iPS injected into CCl4injured mice.
