(A) SCC SBT, c-myc protein cytoplasmic staining in high grade tumor (X400). (B) SCC SBT, EGFR cytoplasmic staining in high grade tumor (X1000). (C) TCC NSBT, bcl-2 nuclear staining high-grade tumor (X400). (D) TCC NSBT, Rb nuclear staining in invasive tumor (X1000). (E) TCC NSBT, ki-67 protein cytoplasmic staining in high-grade tumor (X400). (F) TCC SBT, p53 nuclear stains in low-grade tumor (X1000). (G) SC, p16 nuclear staining (X400). (H) NSC, c-myc cytoplasmic staining (X200).
