Description
Abstract
The proliferation of sheath cells (Schwann
and endoneurium) of growing nerves has been studied
by autoradiography after 3~-thymidinead ministration to
lizards (Anolis carolinensis and Lampropholis delicata)
with regenerating tails. Schwann cells of regenerating
nerves derive from the multiplication of resident cells
within the growing nerves, but labelled Schwann cells
derived from the regenerative blastema also appear to
ensheath the new axons. Endoneurium cells of growing
nerves derive from the blastema around the nerves more
than from dividing and migrating cells of the original
endoneurium. After 6-20 days post-injection the number
of labelled sheath cells in the older proximal regenerated
nerves increased due to local division and migration. In
the proximal spinal ganglia which innervate the
regenerating tail some satellite cells, but not neurons,
took up 3~-thymidinaen d multiplied.
