The results showed that, compared with that in mice of the sh-NC group (control), tumor bioluminescence was significantly low in mice of the sh-CD47 group (bioluminescence difference = -3.82e8 photos/s in shCD47 1#, -2.02e8 in shCD47 2#, **P < 0.01) (Figure 2B, C). Here, CD47 is linked to neoplasm.
