CD19 and cancer: This procedure identifies nine cell types that express specific markers: cancer cells (GFP, Crabp1, Ank), macrophages and monocytes (Cd68, Csf1r, F4/80), DCs (Cd11c, major histocompatibility complex class II (MHCII), c-Kit, Dpp4, Flt3, Btla), group 1 ILCs (Klrb1c/NK1.1, Ncr1/NKp46), Tc (Cd8), Th cells (Cd4), Tregs (Foxp3, Il2ra, Ikzf2), B cells (Cd19, Igkc), and stromal cells (Col1a1, Col1a2) (Figure 1B).
