Image of CiP-induced tumor calcification. a) 3D-reconstructed images and quantitative analysis of lungs from tumor-bearing mice obtained by ex vivo micro-CT scanning; the red box indicates tumor location and calcification signal. b) Schematic of CiP targeting specific cell membranes and inducing calcification. c) Selective adhesion of FITC labeled CiP (200 µg mL⁻¹) on different lung cancer cells. d) The presence of a calcified shell around the cancer cells was confirmed by SEM and element mapping of EDX. e) Small animal CT equipment for taking CT.
