Abstract：
:Differentiation-inducing ability of gamma-radiation, N,N-dimethylformamide and their combination has been tested on human rhabdomyosarcoma RMZ-RC2 clone cells. Ionising radiation at 2-5 Gy doses induced a more differentiated morphology, with the appearance of an increased proportion of multinuclear myotube-like cells, and a significant increase in myosin-positive and multinuclear cells. Radiation appeared to act by inducing de novo differentiated elements. N,N-dimethylformamide was able to induce an increased myosin expression, but did not affect multinuclear cell proportion. The combined treatment (ionising radiation and N,N-dimethylformamide) resulted in an additive increase in the proportion of myosin-positive cells, approaching 25-35%, but de novo differentiated elements were not increased above the levels obtained with irradiation alone.
