摘要: A survey of defined species cell surface and extracellular matrix heparan sulfate proteoglycans (HSPG) was performed in a search for cellular that can promote bFGF receptor binding biological activity. Of the various affinity-purified HSPGs tested, perlecan, large basement membrane HSPG, is found to induce high affinity both cells deficient HS soluble FGF receptors. Heparin-dependent mitogenic activity strongly augmented by perlecan. Monoclonal antibodies perlecan extract promoting from active HSPG preparations. In rabbit ear model vivo angiogenesis, potent inducer bFGF-mediated neovascularization. These results identify as major candidate low affinity, accessory an angiogenic modulator.
