ENPP2 and neoplasm: Bioinformatic analyses revealed five major cell types based on hallmark gene expression: myeloid (Cd11b; 12 clusters), lymphoid (Cd33/Ncr1/B220/Cd19; five clusters), tumor (Olig2/Cd276/Col11a1; one cluster), endothelial (Enpp2; one cluster), and fibroblast (plp1/Ptgds; one cluster) cells (Fig. 4B).
