Fringe proteins and pattern formation

摘要

Isolated DNA encoding a protein or polypeptide having at least one biological activity of a vertebrate fringe protein, as well as the protein or polypeptide encoded thereby, are described. Assays for identifying agents which alter the expression of the described fringe genes and assays for agents which alter the production of angiogenic precursors, the formation of the apical ectodermal ridge and the subdivisions of the neural tube are also described.
