As shown in Figure 2e,f, TAMos derived from spleens of LLC tumor‐bearing mice markedly enhanced TCM cell differentiation as indicated by elevated percentages of CD44+CD62L+ T cells and increased levels of CD62L, CCR7, and IL‐7R expression during T cell antigen‐specific activation compared with vehicle or TANs. This evidence concerns the gene CCR7 and neoplasm.
