Cox-2 and CD68 immunoreactive cells in uninjured nerves and human neuromas. Very few scattered Cox-2 immunoreactive cells were found in uninjured human nerve tissue (A) compared to human neuromas (B). CD68 immunoreative cells were of similar morphology and distribution as Cox-2 and were observed with greater abundance in injured nerve (D) than in control (C). Magnification bars = 50 μm.
