Differential levels of nuclear import factors in the two halves of an early embryo affect gastrulation timing.

, 2019
(A) Experimental approach. One blastomere of a two-cell stage X. laevis embryo was co-microinjected with mRNA to alter nuclear import factor levels and fluorescently labeled dextran as a cell tracer. Embryos were allowed to develop to different stages to

Development of the dendrobatid frog colostethus machalilla

, 2004
To provide a developmental correlate with other frogs, we prepared a normal table of development for the dendrobatid, Colostethus machalilla and analyzed the morphology of its early development. This frog reproduces in captivity and deposits moderately
