In amphibian embryos, the dorsal ectodermal cells in a mid-longitudinal region differentiate to form a neural plate, only when the chorda-mesoderm is below it. Embryonic induction is considered to play an important role in the development of tissues and organs in most animal embryos, from the lower chordates to the higher vertebrates. Introduction. The gradual developmental strategy is known as epigenesis. Neural Patterning. Axis Formation and. Feel free to contact the Admin if you have any doubts or quires.

Vertebrate embryos rely extensively upon inductive interactions to diversify the number of different kinds of cells in the embryo. Induction, or cell-cell communication, is one of the five essential developmental processes, and occurs during development of all animal (and plant) species. Notes on scientific articles.
