After induction and specification in the ectoderm, at the border of the neural plate, the neural
crest (NC) population leaves its original territory through a delamination process. Soon …

We report on the formation and early differentiation of the somites in the avian embryo. The
somites are derived from the mesoderm which, in the body (excluding the head), is …

Fibronectins are large glycoproteins that have been implicated in a wide variety of cellular
properties, particularly those involving the interactions of cells with extracellular materials …

The generation of invasiveness in transformed cells represents an essential step of tumor
progression. We show here, first, that nontransformed Madin-Darby canine kidney (MDCK) …

Invasion causes cancer malignancy. We review recent data about cellular and molecular
mechanisms of invasion, focusing on cross-talk between the invaders and the host. Cancer …

A dialogue between the hippocampus and the neocortex is thought to underlie the
formation, consolidation and retrieval of episodic memories,,,, although the nature of this …

The adhesive extracellular matrix glycoprotein fibronectin (FN) is thought to play an
important role in the cell migration associated with wound healing. Immunolocalization …

The monoclonal antibody HNK-1 was used to identify neural crest cells in serial sections of
avian embryos to provide a detailed description of the distribution of trunk neural crest cells …

Twenty-four embryos of stage 12 (26 days) were studied in detail and graphic
reconstructions of five of them were prepared. The characteristic features of this stage are 21 …

The peripheral nervous system of vertebrates arises from the neural crest and the
ectodermal placodes. Construction of quail-chick chimaeras has provided significant …
