In vitro enrichment of Mo/MΦs using a negative selection human monocyte enrichment kit plus additional depletion of lymphoma cells produced similar results and the three subsets of Mo/MΦs (CD14+SIRPαhi, CD14−SIRPαlow, and CD14−SIRPαneg) were again identified (Fig. 2f). This evidence concerns the gene CD14 and lymphoma.
