Bulbospinal and intraspinal connections in normal and regenerated salamander spinal cord.
TL;DR: In the experiments reported here, HRP application to the lumbar enlargement of normal salamanders labeled cells in the ventral thalamus, the rostral tegmentum in the proposed homolog of the red nucleus, the reticular neurons of the rhombencephalon, and the midline regions of the Rhino nuclei which are possibly equivalent to raphe nuclei of other vertebrates.

Origin of spinal cord axons in the lizard regenerated tail: Supernormal projections from local spinal neurons
TL;DR: Application of HRP immediately rostral to the regenerated spinal cord resulted in the labeling of a normal, and in some cases, greater than normal, number of neurons.

TL;DR: In this paper, a morphometric analysis of electron microscope (EM) photomontages was used to test for changes in synaptic distribution on ventral horn neurons rostral to regenerating tail spinal cord.

Chapter 19 The lizard spinal cord: a model system for the study of spinal cord injury and repair
Sidney B. Simpson,Mark T. Duffy +1 more
TL;DR: This chapter reviews studies on the lizard and comments on results from other systems, inframammalian and mammalian, as they relate to the findings in the lizard, as well as investigating the role of glial cells in lizard cord regeneration.

In vivo test system for tumor production by cell lines derived from lower vertebrates
TL;DR: The immune suppressed lizard, Anolis carolinensis, can be used to test for in vivo tumor production by cell lines derived from a variety of ectothermic vertebrates, demonstrating that the criteria standardly used to assess transformation and neoplastic change in cultured mammalian cells apply equally well to cultured cells from ectotherms.
