Aberrant EphB/ephrin-B expression in experimental gastric lesions and tumor cells

Figure 1 Expression of B-class Eph receptors and ephrin ligands in normal rat gastric corpus mucosa. A: EphB and ephrin-B mRNA expression was determined by reverse transcription-polymerase chain reaction; B: Expression of EphB2-B4, ephrin-B1, and Ki67 in the gastric corpus mucosa was evaluated by immunoperoxidase and hematoxylin and eosin co-staining of frozen sections. Mm: Muscularis mucosae; P: Gastric pit; arrow: Blood vessel.
