Figure Legend Snippet: a, Schematic illustration of the experimental procedure for imaging mouse tissues using COMPASS. Balb/c mice (n=3) were i.v. injected with 4T1 cells in the model groups, while PBS was injected in the control group. The 5-EU (20 mg/ml) was i.p. injected initially, followed by Ac 4 ManNAz (5 mg/kg) once daily for the following three days. b, Images of the lung harvested from mice. Metastatic nodules in the model group are indicated by black circles. Scale bar, 2 mm. c, Hematoxylin & eosin (H&E) staining of tissues from the major organs of control and model mice. Metastatic nodules in the model group are indicated by black circles. Scale bar, 100 µm. d, CLSM images of FRET signals in lung tissues from different treated mice captured with the assistance of COMPASS. The experimental mice were divided into the following two groups (n = 3 per group): a control group and the model group. To establish tumor metastasis models, 4T1 cells (1×10 7 cells) suspended in PBS were injected intravenously through the tail vein in the model group. Meanwhile, the control group was injected with PBS. Mice were labeled with a single or two MCRs (100 μl of 20 mg/ml 5-EU, 0.16 mmole/kg DBCO-AF647), respectively, and subsequent slices were subjected to two-step click chemistry to achieve AF488 and AF647 labeling. Scale bar, 100 µm. e, Intensity surface plots of FRET signals in lung tissues from different treated mice captured with the assistance of COMPASS. f, Quantification of the average fluorescence intensity of nodule versus perinodule regions in the FRET channel on the right side of e . Data in f is representative of three independent experiments; n = 5 frames. Data are shown as mean ± s.d. Statistical significance was analyzed by unpaired t-test; NS, not significant;(*) P < 0.05, (**) P < 0.01, (***) P < 0.001, and (****) P < 0.0001.
