We found PDGFRB is highly expressed in the non‐responding group of mesenchymal‐like cells (Figure 3e; Figure S5a, Supporting Information), previous studies have shown PDGFR family play a significant role in brain, breast, colorectal, melanoma and lung cancers,[22, 23] suggesting that it may be potential marker for treatment response. This evidence concerns the gene PDGFRB and lung cancer.
