Thrombospondins: multifunctional regulators of cell interactions

Annu Rev Cell Dev Biol. 2001:17:25-51. doi: 10.1146/annurev.cellbio.17.1.25.

Abstract

Thrombospondins are secreted, multidomain macromolecules that act as regulators of cell interactions in vertebrates. Gene knockout mice constructed for two members of this family demonstrate roles in the organization and homeostasis of multiple tissues, with particularly significant activities in the regulation of angiogenesis. This review discusses the functions of thrombospondins with regard to their cellular mechanisms of action and highlights recent advances in understanding how multifactorial molecular interactions, at the cell surface and within extracellular matrix, produce cell-type-specific effects on cell behavior and the organization of matrix and tissues.
