Immunohistochemistry of tissue microarray (magnification 400×). Immunoreactivities of CDC2 (A-C) and TUNEL (D-F) in xenogeneic graft tumor specimens were examined. IRS of CDC2 are negative in tumors treated with recombinant C3 retrovirus (-) (A); positive in tumors treated with saline (++) (B); also positive in NO.12 tumor (C). IRS of TUNEL are positive in tumors treated with recombinant C3 retrovirus (++) (D); negative in tumors treated with saline (-) (E); also negative in NO.12 tumor (-) (F).
