There was some experiment in which a S phase cell was fused with other cell and the other cell also began to replicate DNA. Would the same happen if fused with nerve cell ? Why or why not?

fusing cells is not feasible in all cases (it also causes polyploidy).. cells are immortalized by using oncogenes.. –  WYSIWYG Oct 7 '13 at 18:58

Just an addition to the WYSIWYG's answer: phenomenon of neuronal de-differentiation under the influence of oncogenes was shown. –  har-wradim Oct 8 '13 at 18:12
Thanks for pointing @har-wradim. Now I remember that I heard a talk by that paper's author explaining the same. –  WYSIWYG Oct 10 '13 at 7:41
