Figure 6From: Acute injury in the peripheral nervous system triggers an alternative macrophage response Arginase-1 positive cells in the injured peripheral nerve tissue are macrophages. Double immunofluorescently stained peripheral nerve sections at day 0, day 1, day 3, and day 14 upon axotomy showing arginase-1 colocalizing with F4/80, a general macrophage marker. F4/80, red; S100, red; arginase-1, green. Scale bar 20 μm.Back to article page
