In this review article, the traditional viewpoint of how neurulation occurs is evaluated in light
of recent advances. This has led to the formulation of the following fundamentals:(1) …

Molecular and cellular mechanisms of epithelial–mesenchymal transition (EMT), crucial in
development and pathogenesis, are still poorly understood. Here we provide evidence that …

Neurulation, formation of the neural tube, a crucial event of early embryogenesis, is believed
to be driven by the coordination of a number of diverse morphogenetic cell behaviors. Such …

The objective of this study was to investigate the impact of stimulating the embryo during the
dormancy in the incubation period. 450 eggs (Ross 308) were allocated in four treatments …

Early stages of avian development are not well‐suited for in ovo studies. A critical limitation
of ex ovo culture is the short period of growth that can be attained for explanted embryos …

Epithelial to mesenchymal transition (EMT) is a morphogenetic process in which cells lose
their epithelial characteristics and gain mesenchymal properties, and is fundamental for …

After some introductory remarks about vertical versus horizontal inductive interactions and
about planar versus homoiogenetic induction, the author discusses: a) the historical …

In this essay, I will focus on both gastrulation and neurulation in avian embryos. The two
processes are driven by similar cell behaviors: cell shape changes, cell division, and cell …

McWhorter and Whipple (1912) are reported to be the first to have succeeded in culturing
early (primitive streak stage) chick embryos in vitro. However, most of the important studies …

Publisher Summary The chapter discusses the role of cell rearrangement in processes as
diverse as chick neurulation, archenteron formation, elongation in sea urchin gastrulation …
