Figure 2 Schematic diagram of immunogene therapy. A: Immunogene therapy with altered cancer cells, which are harvested from patients (autologous cells) or from established cancer cell lines (allogeneic) and then cultured in vitro and inactivated to yield a vaccine; B: Immunogene therapy with in vivo gene transfer; C: Immunogene therapy using altered immune cells.
