## Abstract A perfusion technique is described for the study of melanosome response in ventral tailfin melanophores of __Xenopus laevis__ tadpoles. The melanosomes remain aggregated (punctate melanophores) in Ringer's. Theophylline (15 mM) and caffeine (30 mM) cause a reversible dispersion (stellat
## Abstract The effects of cytochalasin B or low concentrations of adenosine 3β²,5β²βmonophosphate (cyclic AMP) were tested on melanophores in hanging drop preparations of neural fold explants from __Xenopus laevis__ embryos in Barths' solution. After one week in culture, the melanophores were puncta
