Abstract

Five distinguishable stages of tail regeneration in the adult newt have been established. The stages are based on external morphological changes and internal histological characteristics rather than chronological age of the regenerate.

## Abstract Some aspects of the influence of position on regeneration have been examined by comparing regeneration from different levels along the newt tail. Tails amputated such that either three‐fourths, one‐half or one‐fourth of the tail was removed pass through the same morphological and histol

## Abstract Radioimmunoassay (RIA) procedures were used to determine whether or not insulin is present in the adult newt. The results show that measurable amounts of the hormone are present in samples ofpooled, fresh serum taken by cardiac puncture methods. We also found that there are no significa

Spinal axons of the adult newt will regenerate when the spinal cord is severed or when the tail is amputated. Ischemia and associated hypoxia have been correlated with poor central nervous system regeneration in mammals. To test the effects of ischemia on newt spinal cord regeneration, the spinal co

## Abstract Cyclophosphamide (cytoxan), a clinical immunosuppressant, produced a marked, persistent leukopenia (> 40% reduction) in adult newts in contrast to a transient, milder leukopenia accompanying amputations without cytoxan treatments. In addition, cytoxan suppressed the formation of regener

The concentrations of thyroxine (TJ and triiodothyronine (T,) were determined on samples of fresh sera from adult male and female newts during the course of forelimb regeneration by means of radioimmunoassay (RIA) methods. The results show that the circulatory levels of T, and T3 in males and female

## Abstract Subsequent to excision and explantation of the limb blastema into culture medium, there is an abrupt reduction in mitotic index lasting several hours. Coincident with the disappearance of mitosis, abnormal mitotic figures (AMFs), lacking the condensed chromosomal nature of normal figure
