The presumptive territory of the mesoderm in the ascidian germ

1955

Col metodo delle marche con granuli di gesso colorato, sono stati modificati gli schemi diConklin riguardanti i territori presuntivi del mesenchina e della muscolatura nel germe di Ascidie.

Incorporation of phenylalanine-H3 in the fragments of the fertilized ascidian egg

1972

E'stata studiata l'incorporazione di fenilalanina-H3 nelle meta animali e vegetative delle uova fecondate di Ascidie tagliate subito dopo l'emissione del 1° e del 2° globulo polare, allo scopo di vedere se le potenzialita di sviluppo delle meta vegetative fossero legate con un diverso metabolismo proteico. I risultati hanno mostrato che entrambe le meta incorporano fenilalanina-H3.

Binding of concanavalin A to the surface of unfertilized and fertilized ascidian eggs.

1973

STUDIES with certain carbohydrate-binding proteins of plant origin (as concanavalin A and wheat germ agglutinin) have indicated that some surface properties of embryonic1,2 and of virally transformed cells3–6 are different from those of adult cells. The interpretation of the differences in terms of structural organization of the cell surface is, however, still controversial (see for example refs. 7 and 8).
