Directed axonal outgrowth using a propagating gradient of IGF-1 ADVANCED MATERIALS Lee, W., Frank, C. W., Park, J. 2014; 26: 4936–4940

Abstract

The temporospatial regulation of axon outgrowth is useful for guiding de novo connectivity or re-connectivity of neurons in neurological injury or disease. Here we report the successful construction of a biocompatible guidance device, in which a linear propagation of IGF-1 gradient sequentially directs axon outgrowth. We observe the extensive in vitro axonal extension over 5 mm with a desired growth rate of ~1 mm/day.
