Patent ID: 7947651

Claim:
An isolated polypeptide comprising a fragment of the amino acid sequence set forth as SEQ ID NO: 3, wherein the fragment consists of an amino acid sequence selected from the group consisting of: (a) a polypeptide fragment of secreted frizzled related protein (sFRP) denoted sFRP-Δ1 having an amino acid sequence at least 95% homologous to the amino acid sequence shown in residues 1-171 of SEQ ID NO: 5; (b) a polypeptide fragment of secreted frizzled related protein (sFRP) denoted sFRP-Δ2 having an amino acid sequence at least 98% homologous to the amino acid sequence shown in residues 1-221 of SEQ ID NO: 6; and (c) a polypeptide fragment of secreted frizzled related protein (sFRP) denoted sFRP-Δ3 having an amino acid sequence at least 98% homologous to the amino acid sequence shown in residues 1-242 of SEQ ID NO: 7.
