Pathfinding by neuronal growth cones in grasshopper embryos. III. Selective affinity of the G growth cone for the P cells within the A/P fascicle
MJ Bastiani, JA Raper and CS Goodman
The growth cone of the G neuron selectively fasciculates upon specific axon
bundles in a stereotypic sequence as it navigates through the developing
central nervous system of the grasshopper embryo. It turns and extends
anteriorly in the contralateral neuropil of the second thoracic ganglion at
a specific choice point where it fasciculates with the A/P axon bundle
which contains the axons of the A1, A2, P1, and P2 neurons. We previously
hypothesized (Raper, J. A., M. J. Bastiani, and C. S. Goodman (1983) J.
Neurosci. 3: 20-41) that this fascicle, or subsets of axons within it, were
specifically labeled and that the G neuron was determined to follow this
labeled pathway. Here we report on an ultrastructural analysis of the
interactions between the G growth cone and its filopodia with the cells of
the A/P fascicle at the choice point. As G reaches its choice point, its
filopodia are in more frequent contact with the A/P fascicle in comparison
to the other longitudinal axon fascicles. Within the A/P fascicle, the tip
of G's growth cone is found to be closely associated with the P and not the
A axons. Furthermore, before the G growth cone climbs onto the A/P
fascicle, its filopodia show a selective affinity for the P axons as
compared to the A axons. Another specific interaction involves selective
filopodial insertions; only filopodia from the P cells were found to insert
into the G growth cone and induce coated pits and vesicles. These findings
suggest that G is able to distinguish the A/P fascicle from other axon
bundles and, moreover, is able to distinguish the P axons from the A axons.
The companion paper (Raper, J. A., M. J. Bastiani, and C. S. Goodman (1984)
J. Neurosci. 4: 2329-2345) presents experimental results based on specific
axon ablations that further support this hypothesis.
