Vi visa upp utvecklingen av själv monterade, tredimensionell buntar av längdriktningen justerad astrocytic somata och processer inom en roman biomaterial fodral. Dessa konstruerade ”levande ställningar”, uppvisar micron-skala diameter ännu att utvidga centimeter i längd, kan fungera som test-sängar att studera nervsystemets mekanismer eller underlätta neuroregeneration av rikta neuronala migration och/eller axonal pathfinding.
