B0003229 Dorsal Root Ganglion neuron growth cones

Close up of the growth cones of dorsal root
ganglion nerve cells. They are stained to reveal
the microtubules (green) and actin filaments
(red). The axon shaft contains bundles of
microtubules that give structural support and
carry cargo (protein and membranes) to and from
the cell body. The “hand-like” growth cones at the
end of the axons are very motile and read and
integrate molecular cues in the environment. They
also guide the growing nerves to their targets in
the growing embryo.
