Patent ID: 7041312

Claim:
A wound-healing composition, comprising: a wound-treating component; and fusogenic vesicles, wherein the vesicles comprise: a phospholipid which is a stable vesicle former, wherein the phospholipid is a phosphatidylcholine; at least one unstable vesicle forming member, wherein the unstable vesicle forming member is PEG or polar lipid having the structure of formula (I) X-L-Z 2 (I) wherein X is H or a head group comprising a polar group selected from the group consisting of formulas (III), (IV), (V), (VI), and (VII) L is an alkyl further missing two hydrogen atoms, and each Z is independently H, E, or the structure of formula (XI), wherein E is an alkyl or alkenyl, and when one Z is H, the other Z is not H; and ATP at a concentration of 1 mM to 50 mM, wherein the vesicles have a ratio of the stable vesicle former to the unstable vesicle forming member of 1:1 to 500:1 and a fusion rate of at least 20 vesicle fusions/second.
