Changes of the cell surface charge of amphibian ectoderm after induction


Isolated ectoderm of early gastrula stages ofTriturus alpestris was treated with vegetalizing factor for 24 h employing the sandwich method (induced ectoderm). Controls were incubated for the same period with γ-globulin which has no inducing activity. Explants of both series were labelled with cationized ferritin, which binds to negatively charged groups at… (More)
