CSF3R and gastric neoplasm: To shed light on myeloid populations present in gastric tumors, we re-clustered the 10,546 myeloid cells in our dataset and identified fifteen subclusters which were subsequently determined to be either macrophages (CD68, CD14), dendritic cells (FLT3, FCER1A), or neutrophils (CSF3R) (Fig. 4a).
