Electric field-induced astrocyte alignment directs neurite outgrowth.
This in vitro study examined whether astrocyte alignment induced by an applied electric field influences neurite outgrowth. Astrocytes were pre-aligned using a physiological-strength electric field (500 mV mm(-1)), and dorsal root ganglia cells were then seeded onto them. Neurite outgrowth at 24 and 48 hours was reported to be significantly enhanced and consistently directed along aligned astrocyte processes, including on fixed aligned astrocytes.
Key points
- Astrocytes in culture were pre-aligned by exposure to an electric field described as physiological strength (500 mV mm(-1)).
- Dorsal root ganglia cells seeded onto aligned astrocytes showed enhanced neurite outgrowth at 24 and 48 hours.
- Neurite extension was directed along the orientation of aligned astrocyte processes.
- Directed neurite outgrowth persisted when neurites were grown on fixed, aligned astrocytes.
- The authors suggest endogenous electric fields in the developing CNS might align astrocyte processes and thereby promote neurite growth.
- The abstract does not report sample size or detailed exposure timing parameters.
