Impact of fibroblast growth factor-binding protein-1 expression on angiogenesis and wound healing.

ABSTRACT: Fibroblast growth factors (FGFs) participate in embryonic development, in maintenance of tissue homeostasis in the adult, and in various diseases. FGF-binding proteins (FGFBP) are secreted proteins that chaperone FGFs stored in the extracellular matrix to their receptor, and can thus modulate FGF signaling. FGFBP1 (alias BP1, FGF-BP1, or HBp17) expression is required for embryonic survival, can modulate FGF-dependent vascular permeability in embryos, and is an angiogenic switch in human cancers. To determine the function of BP1 in vivo, we generated tetracycline-regulated conditional BP1 transgenic mice. BP1-expressing adult mice are viable, fertile, and phenotypically indistinguishable from their littermates. Induction of BP1 expression increased mouse primary fibroblast motility in vitro
