In vivo tumor formation assay. Each transfectant, HSC2 or HSC2/EGFP (1 × 104) were inoculated into BALB/c nude mice subcutaneously and tumor volume was measured once a week for 4 weeks. a Change of tumor volume. Error bars represent the standard error of the mean from three mice results (n = 3). b Nude mice tumor at 2 weeks after 1 × 104 cells injection. c Nude mice tumor at 4 weeks after 1 × 104 cells injection (Bar  =  10 mm). Arrows show the tumor mass
