In this model organism, actomyosin contractility near the dorsal marginal zone drives apical constriction in bottle cells, which are formed through invagination during gastrulation.
In this model organism, actomyosin contractility near the dorsal marginal zone drives apical constriction in bottle cells, which are formed through invagination during gastrulation. One commonly used assay in this organism involves cutting cells near its cement gland and moving them elsewhere. In this organism, Wnt signaling occurs from the Nieuwkoop  ("NEW-cop") center, which in turn gives rise to the set of cells responsible for dorso-ventral and antero- posterior axis formation, called the Spemann-Mangold organizer. Because organisms in this genus have a large brood size and eggs over 1 mm in diameter, they are useful for studying embryological development. Tropicalis and laevis are species of , for 10 points, what model organism, commonly called the African clawed frog?
