Abstract
This invention provides VEGF-FSH compounds having increased serum half-lives relative to either native VEGF or FSH, in which both VEGF and FSH are biologically active. This invention also provides related compositions and methods for increasing fertility, egg production and spermatogenesis in a subject, as well as methods for increasing vascularization in a tissue, particularly in ovarian tissue.
Claims1
A method for increasing vascularization in a tissue by contacting the tissue with an amount of a composition of matter comprising (a) at least one subunit of a hormone or growth factor selected from the group consisting of VEGF, GH, TGFα, TGFfβ1, EGF, FGF, SCF, IGF-I, IGF-II, GDF-9, KGF, GM-CSF, LIF, follistatin, a neurotropin, angiopoiten I or II, MCP-1 and (b) a serum half-life-increasing moiety, wherein the hormone or growth factor subunit and serum half-life-increasing moiety are covalently bound, and wherein the serum half-life-increasing moiety is a polypeptide comprising the amino acid sequence ser-gly-ser-asn-ala-thr-gly-ser-gly-ser-asn-ala-thr-ser-gly-ser (SEQ ID NO:9), effective to increase vascularization in the tissue.
