Abstract

The invention is directed to a method for the preparation of a conditionally immortalized immortalization-helper cell (fuseme), the fusemes generated by said method, hybridoma cells prepared using said fusemes as well as a method for immortalization of mammalian cells using said fuseme cells. Further, the invention relates to the generation of T cells directed agaist tumor cells using a fuseme cell.
