EphA2 and ephrinA1 expression in the present case. Immunohistochemistry for EphA2 (A) and ephrinA1 (B). Note that EphA2 (A) staining is positive in the tumor cell, while ephrinA1 (B) is negative. Original magnification × 200. (C), EphA2 was identified in the frozen tissue by reverse transcription-PCR, with higher mRNA expression in the tumor than normal salivary gland.
