WebDec 24, 1996 · We have shown previously in an in vitro “choice assay” that chicken dorsal root ganglion (DRG) growth cones turn when confronting a sharp substrate border between a permissive (laminin) and a nonpermissive (tenascin) substrate (5, 6).At the border, growth cones make turns and grow along the laminin side. Tenascin (tenascin-C, see ref. 7) is a … WebWe have found that Epac is required for cAMP-dependent axon growth and regeneration and its activation promotes axon regeneration in vitro more potently than activation of cAMP itself. Additionally, growth cone turning assays have revealed that Epac and PKA have distinct roles in regulating axon guidance.
