Certain tissues such as cartilage are resistant to vascular invasion, yet no single tissue-
derived molecule that can inhibit angiogenesis has been reported. A protein derived from
cartilage was purified that inhibits angiogenesis in vivo and capillary endothelial cell
proliferation and migration in vitro in three separate bioassays. This protein is also an
inhibitor of mammalian collagenase. These findings may help elucidate the mechanisms by
which neovascularization is controlled in both normal and pathological states.
