Dorsal root ganglion neurons from embryonic rats, co-cultured with endoneurial explants from transected, adult rat sciatic nerve. extended neurites in the absence of exogenous nerve growth factor (NGF). The effect was seen with endoneurial explants from normal adult sciatic nerves or from nerves which had been permanently transected up to 51 days prior to explantation. The rate of outgrowth decreased at 5 and 7 days and reached a minimum at 14 days after transection. A second phase of increased neurite-promoting activity appeared in 28-, 35-, 41- and 51-day posttransection tissue. The early phase, but not the late phase, was partially inhibited by antisera to NGF.
