PTX + CDDP induce LLC cell apoptosis in vitro but not in vivo at the same concentration. (A) LLC cells were examined by micro-imaging and Tunel assay. PTX + CDDP induced LLC cell apoptosis in vitro (original magnification, ×200; scale bar, 50 μm). (B) Cryosections of tumor tissues were examined by Tunel. No apoptosis was detected in vivo in PTX + CDDP groups (original magnification, ×100; scale bar, 100 μm). (PDF 129 kb)
