The results demonstrated that the mean density of c-Myc in the tumor sections prepared from the IFNα-AF-MSC-engrafted mice (0.0223 ± 0.0101, n = 5) was significantly lower than that of the control group (0.0374 ± 0.0064, n = 5, P < 0.05), but no significant differences were observed between either of the other 2 groups. The gene discussed is IFNA1; the disease is neoplasm.
