膠質瘢痕與功能再生（3）

       第三屆國際神經再生高峯論壇(INRS2013)——While the astrocytic scar is one major barrier to regeneration, regeneration failure is also due in part to the synaptic entrapment of growth cones on NG2 glia (following MAC attack) through actions of LAR family receptors that cause an overly adhered synaptic state. Inactivation of LAR or PTP sigma in our scar model in vitro releases entrapment and allows for motile growth cones.
