Tumorigenic Potential of MSC-lung Carcinoma Hybrids.

Note: Data are given as number/total (percentage). Control MSCs implanted alone into 10 mice (inoculum, 1×106 cells/mouse) were nontumorigenic. *Statistically significant difference by two-sided Fisher’s exact test with respect to the rate of tumor incidence by parental lung cancer cells (P<0.001).
