In vivo antitumor effect of MSCs‐LDGI (intratumoral injection). a) In vivo photoacoustic image, Prussian blue staining, and silver‐enhanced staining of tumor tissues of LDGI and MSCs‐LDGI, respectively. b) Infrared thermal images and c) temperature increasing curves of PBS, LDGI, MSCs‐LGI, and MSCs‐LDGI with continuous laser irradiation of 808 nm laser (1.5 W cm⁻², 10 min) in vivo. d) Relative tumor volume and e) images of mice of being intratumorally injected with DOX, PBS, LDGI, MSCs‐LGI, MSCs‐LDGI with and without NIR laser irradiation within 15 days.
