Enhanced tumorigenicity of the fused cells was detected in nude mice. The in vivo test for tumorigenicity of the fused cells. a Mice injected with the fused cells (top line) and HepG2 (bottom line) in the number of 5 × 10⁴ and 1 × 10⁵. Red arrows indicate the tumors from the fused cell, whereas in the control group, no tumor was found. b Tumors stripped from the corresponding mice
