The glia cell rings expressing p75NTR were presented around the neurons of DRG in adult rats (a) but not in pups (b) at postoperative day 7. Glial p75NTR was observed at postoperative day 28 in pups (c). Solid arrows: SCG rings expressing p75NTR; hollow arrow: neurons expressing p75NTR at the nucleus. Scale bars: 100 μm.
