...J.E. Foret; G.L. Babich The effects of dibutyryl cyclic AMP and other agents related to cyclic AMP metabolism on DNA synthesis by cultured newt limb regeneration blastemas were studied. Dibutyryl cyclic AMP stimulated thymidine incorporation in both early and late stages of regeneration, although...

...G.L. Babich; J.E. Foret Dibutyryl cyclic AMP or sodium fluoride was found to stimulate 14 C-leucine incorporation by newt limb regeneration blastemas in vitro . The increased amino acid incorporation was observed in both the mound stage blastema and the more advanced palette stage regenerate...

A significant reduction in leucine incorpo- Protein synthesis ration was observed in experimental cultures, particularly at the earlier...

... cells from 18 day limb regenerates revealed an S-phase duration of 30–55 hours and a cycle time of 45–60 hours for these two tissues. Grillo and Urso (1968) reported an S-phase duration of 55 hours and a cycle time of 75 hours for newt intestinal epithelium. Following the loss of an appendage...
