We show that these cells infiltrate and possibly predispose the local microenvironment for the successful settling of disseminated NRAS‐mutant tumor cells, and include CD45+CD11b+Ly6c+ and CD45+CD11b+Ly6g+ hematopoietic as well as CXCR2+CD34+ endothelial progenitors. Here, PTPRC is linked to neoplasm.
