FLT3 and neoplasm: Quantification of distinct subsets of myeloid progenitors and mature myeloid cells in the bone marrow of tumor-bearing Shp2f/f and Shp2f/fLysMCre mice at day 9 post implantation of MC17-51 tumors, before isolation of monocytes and neutrophils for adoptive transfer, showed similar number of Lin− myeloid progenitors including Flt3+CD115lo CMP, FLT3−CMP, MDP, GMP, GP, MP+cMoP or mature differentiated Lin+ myeloid cells, including total CD45+CD11b+ myeloid cells, CD11b+Ly6ChiLy6G− monocytes and CD11b+Ly6CloLy6G+ granulocytes at this timepoint (Fig. 6c,d and Extended Data Fig. 5).
