From: Microglial responses around intrinsic CNS neurons are correlated with axonal regeneration
Histogram showing the number of CD11b-positive microglia per mm2 in the red nucleus following axotomy alone or insertion of a peripheral nerve graft into the rubrospinal tract. Axotomy (grey columns) has little effect on microglial numbers whereas insertion of a peripheral nerve graft into the rubrospinal tract to induce axonal regeneration (black columns) produces a prolonged increase in the number of microglia within the red nucleus. The results are from 4 animals in each case (*P < 0.05).
