| 摘要 |
The present invention provides a multimeric form of a Tie 2 binding peptide monomer, wherein the multimeric form has Tie 2 agonist activity. The multimeric form, preferably a tetramer, stimulates angiogenesis and promotes wound healing. The present invention also features pharmaceutical compositions comprising the multimeric Tie 2 agonists, including those suitable for topical or systemic administration. Methods of using the multimeric Tie 2 agonists of the invention for stimulating angiogenesis and for promoting healing of wounds, such as diabetic ulcers or skin grafts, are also provided.
