In addition, we also found that the anti‐TCR‐γδ antibodies staining in spleen sections showed more positive cells in the GCP‐treated group (Fig. 4A), and the number of tumor‐infiltrated CD27+γδT cells increased significantly in the GCP‐treated group compared to the Model group (Fig. 4B, Fig. S1b). This evidence concerns the gene CD27 and neoplasm.
