The antitumor effect by the adoptive transfer of T cells and immunoglobulins in vivo. (A,C) Treatment with T cells isolated from pcDNA3.1‐Xenopus receptor for hyaluronic‐acid‐mediated motility (xRHAMM)‐immunized mice showed apparent protective antitumor effect, compared with controls, to local tumors and lung metastasis. However, there was mild protective effect for the adoptive transfer of immunoglobulins in vivo (B,D). (A,B) The subcutaneous local tumor model; (C,D) lung metastasis model.
