The results showed that the targeted deletion of host Stk10 does not affect the percentage of tumor-infiltrated neutrophile granulocytes (CD45+CD11b+Gr-1+), macrophages (CD45+CD11b+F4/80+), NK cells (CD45+NK1.1+), NKT cells (CD45+NK1.1+CD3+) and B cells (B220+). This evidence concerns the gene PTPRC and neoplasm.
