As DDR1 also activates kinase‐independent signalling cascades to induce collective migration or extracellular matrix degradation of tumour cells and metastasis reactivation of disseminated tumour cells (Hidalgo‐Carcedo et al, 2011; Juin et al, 2014; Gao et al, 2016), we propose that DDR1 induces both kinase‐dependent and ‐independent pathways to fully promote metastasis formation. Here, DDR1 is linked to neoplasm.
