CALCA and neoplasm: Finally, flow cytometry analysis showed that a subset of tumour cells coexpressing CD47bright and markers previously associated with metastatic potential such as CD9 and CD13332,33 (Extended Data Fig. 1l) and endowed with metastatic potential in vivo and in vitro (Extended Data Fig. 1m) is increased by around tenfold in the liver of KC-deficient Clec4fcreR26LSL-DTR mice in comparison to in their littermate controls (Extended Data Fig. 1n).
