Structure and Function of Cadherins,, particularly with the remodeling of epithelia and the segregation of cell collectives. Several cadherins are expressed in each cell type simultaneously, although in a defined repertoire and with variable levels of expression. These different combinations of cadherins are likely to be responsible for distinct adhesive properties of cells.

The Formation of Mesoderm and Muscle in ,,ve been more fully investigated in . than in any other organism. The conclusions which come from its study are therefore likely to be a guide to the understanding of equivalent tissues and activities in the other vertebrates.

The Role of Insulin-Like Growth Factor II in the Growth and Development of the Mammalian Embryo,acrine mode. These embryonic polypeptide growth factors are usually identical to growth factors isolated from serum or tissues of adult animals. Insulin-like growth factor II (IGF-II) (for a review see Schofield, 1992) is one of the growth factors playing a significant role in the development of the mammalian embryo.

Regulation of Cell Fate by Processed Vg1 Protein,gh doses mature Vg1 induced formation of “embryoids” with a rudimentary axial pattern, head structures including eyes, and a functional neuromuscular system. Furthermore, truncated forms of the activin and FGF receptors, which block mesoderm induction in the intact embryo, fully inhibited mature Vg1

In the adult, the ECM is confined to basement membranes. This paper focuses on the biological activity of laminin and its expression in the early embryo. The appearance of laminin
