CFB and neoplasm: Previous studies have reported two main mechanisms of pericytes for promoting tumor growth and metastasis, one is the pericyte‐CAF transition induced by PDGF‐BB‐PDGFRβ signaling,[27] which is also consistent with our observations in the present study that PDGFRB is upregulated in pericytes and similarity between pericytes and CAFs in UMAP clustering plot (Figure 4a,b).
