Recent Studies of Embryonic Induction
New England Journal of Medicine, 1963SINCE the beginning of experimental embryology the student interested in the developing organism has puzzled over the complex cellular movements and interactions by which a single ovum organizes itself into a multicellular animal. Indeed, the first experiments that were done on embryos were concerned with this problem. Wilhelm Roux, in 1888, killed one

The sodium dependence of embryonic induction
Developmental Biology, 1969Abstract Induction of nerve and pigment cells in presumptive epidermis of the frog gastrula has been found to be dependent upon the concentration of the sodium ion. This sodium dependence is shown by small aggregates of presumptive epidermis cells induced by sucrose or by ions (Li+, Ca2+, Mg2+, Mn2+) to differentiate into nerve or pigment cells ...

Inductive interactions in early embryonic development
Current Opinion in Genetics & Development, 1991This is an update of a previous review (Current Opinion in Cell Biology 2:969-974) in which we discussed recent work attempting to understand the sequence of inductive interactions responsible for establishing the body plan of the early embryo. As before, we concentrate on inductive interactions in amphibian embryos, where significant progress has been

1984
In 1923 it was discovered by Hilde Mangold and Hans Spemann that the blastoporal lip, the presumptive mesodermal anlage, induces in ventral ectoderm a second neural anlage. In normal development ventral ectoderm does not form any nervous tissue but epidermis.

Dialectics, systems biology and embryonic induction
Differentiation, 2011A hallmark of embryonic development is the temporal-spatial continuum of cell-cell interactions, which gives rise to the trajectory of progressive cell differentiations. Despite the great reductionists' success in dissecting the mechanistic basis of developmental processes, the call for more holistic system theories never ceased during the last century.

EMBRYONIC INDUCTION IN THE ASCIDIA
The Biological Bulletin, 1939The Ascidia are grouped with those animals whose early development is termed mosaic. Yet, in the closely related Vertebrata, organs form as the result of interaction between those cells which become the definitive organ in question and neighboring cells, whose descendants take no part in the actual formation of the organ.
