Figure Lengend Snippet: Comparison of the mouse hindlimb vascular network visualized by micro-CT or by iDISCO + clearing and light-sheet imaging (A and B) Anterior view of representative micro-CT images of the mouse hindlimb following perfusion with Vascupaint contrast agent and an LSFM image of a mouse hindlimb perfused with lectin-649 and cleared using iDISCO + . Bone in the micro-CT images is pseudocolored white, while vessels in both the micro-CT and light-sheet panels are color coded based on vessel diameter (the keys corresponding to vessel diameter are to the right of [E and F]). (C and D) Medial and (E and F) lateral views of the same samples. (G) Quantification of the frequency of different diameter vessels in micro-CT and LSFM-imaged samples, with error bars showing mean ± SEM. (H) Quantification of the difference in vessel volume relative to the sample volume (calculated as vessel volume ratio (%) = V e s s e l v o l u m e S a m p l e v o l u m e × 100%) between micro-CT and LSFM-imaged samples, with error bars showing mean ± SEM. F, femur; Fi, fibula; P, patella; T, tibia; IMGA, inferior medial geniculate artery; ILGA, inferior lateral geniculate artery; PA, popliteal artery; SMGA, superior medial genicular artery; SLGA, superior lateral genicular artery). n = 5 samples per group (2 month-old mice); t test, ∗∗∗∗ p ≤ 0.0001.
