PTPRC and neoplasm: Compared with the untreated mice, the CD45+ cells are slightly increased (without statistical significance) in DCG spore treated mice; the percentages of T cells, infiltrating to tumour, are slightly increased in DCG spore treated mice, while B220+, NK1.1+, and F4/80+ cells are similar among the DCG treated and nontreated groups (Figure 3).
