CX3CR1 and neoplasm: When the CX3CR1 status was considered, we found that APC+/min-CX3CR1-/- mice showed a slightly but significant increased accumulation of IntegriSense750 probe compared to APC+/min-CX3CR1+/- mice both in in vivo FMT and ex vivo imaging analysis (Figure 3A, 3B and Figure 3C, 3D, respectively), confirming our (and other) previous results of increased tumor occurrence in CX3CR1-deficient mice [20, 22].
