Demonstration of sensory-motor innervation of postmetamorphic forelimb regenerates of Triturus alpestris (Urodela) on cryotome serial sections using horseradish peroxidase.
A method has been developed to obtain horseradish peroxidase-treated serial sections containing spinal cord as well as bilateral ventral and dorsal roots, dorsal root ganglia and spinal nerves. Young postmetamorphic newts (Triturus alpestris) served as experimental animals. After cryotome cross sectioning the forelimb region of the trunk, slices 80 microns in thickness were mounted serially with up to 15 sections per slide. This facilitated subsequent staining manipulations and made partial loss of sections less likely.
