## Abstract Experiments were performed in vitro to assess the mitogenic activity of brain homogenates and cyclic nucleotides on adult newt limb blastemal cells. Early cone stage blastemata were explanted into organ culture, and thus denervated. The mitotic index (M.I.) of each was calculated and sh

Removal of the lens from the eye of an adult newt (Notophthalmus viridescens) is followed by regeneration of a new lens from the dorsal iris epithelial cells at the pupillary margin. This process is dependent upon the neural retina for its normal completion in vivo and in vitro. To examine the relat
## 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 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
