Analysis of cell size in the gastrula of ten frog species reveals a correlation of egg with cell sizes, and a conserved pattern of small cells in the marginal zone

Del Pino Veintimilla, Eugenia; Vargas, Alexandra (10/07/2016)

We investigated the relationship between egg and cell sizes in the early gastrula of ten species of frogs with eggs of 1,100-3,500 μm diameters. We asked whether differences in cell size of the vegetal region, blastocoel ...
Development and gastrulation in Hyloxalus vertebralis and Dendrobates auratus (Anura: Dendrobatidae).

Del Pino Veintimilla, Eugenia (22/03/2015)

We document the embryonic development of Hyloxalus vertebralis, a frog species of the Ecuadorian highlands, declared as Critically Endangered by the International Union for the Conservation of Nature (IUCN) due to significant ...
Developmental diversity of amphibians.

Del Pino Veintimilla, Eugenia (2012)

The current model amphibian, Xenopus laevis, develops rapidly in water to a tadpole which metamorphoses into a frog. Many amphibians deviate from the X. Laevis developmental pattern. Among other adaptations, their embryos ...
The gastrocoel roof plate in embryos of different frogs.

Del Pino Veintimilla, Eugenia (2012)

The morphology of the gastrocoel roof plate and the presence of cilia in this structure were examined in embryos of four species of frogs. Embryos of Ceratophrys stolzmani (Ceratophryidae) and Engystomops randi (Leiuperidae) ...
La placa del techo del gastrocele de Epipedobates tricolor (Anura: Dendrobatidae).

Del Pino Veintimilla, Eugenia (2012)

En la mayoría de los vertebrados usados como modelo del desarrollo, la determinación de la asimetría izquierda-derecha de la localización de órganos tales como el corazón se determina en la neurula y obedece a un flujo de ...
Variation in the schedules of somite and neural development in frogs.

Del Pino Veintimilla, Eugenia (2012)

The timing of notochrod, somite, and neural development was analyzed in the embryos of six differnt frog species, which have been divided into two groups, according to their developmental speed. Rapid developing species ...
