The culture of explanted neural tissues has been a useful tool for the stud
y of cellular and molecular neurobiology in vertebrates. We have developed
a technique for the culture of explanted ventral nerve cords from Drosophil
a embryos. We have examined the morphology and dynamic behaviour of the gro
wth cones that extend from these nerve cords, and the effect of calcium dep
rivation on the bundling of axons that are regenerated from the explanted t
issue. This technique offers a unique opportunity to combine in vitro techn
iques for neuronal cell culture with the powerful techniques of genetic ana
lysis that are available with Drosophila. (C) 1998 Published by Elsevier Sc
