ABSTRACT
Explant systems and vital staining have been used to study the specific effects of various concentrations of β-mercaptoethanol on the morphogenetic movements of amphibians. Three different types of effect were observed.
(a) rapid but reversible inhibition of neurulation, becoming irreversible after prolonged treatments;
(b) slow, progressive inhibition of epiboly, convergent stretching and ingression;
(c) very slight inhibition of invagination, occurring only at high concentrations or after prolonged treatments.
The significance of these results is discussed.
