Recombinant Human Wnt-3a Protein

Description
The Wnts is a large family of secreted proteins with roles in pattern formation, cell fate decision, axon guidance, and tumor formation. Wnt signaling induces and maintains the transformed phenotype and, in certain embryonic cell lines, supports self-renewal in the absence of significant differentiation. Elevated levels of Wnt proteins are associated with tumorigenesis and are present in numerous human breast cancers. Wnt family members are highly hydrophobic, and possess 22 to 24 conserved cysteines.
Wnt-3a is necessary for proper development of the hippocampus, anterior-posterior patterning, somite development, and tailbud formation. Wnt-3a also promotes self-renewal of hematopoietic stem cells, neural stem cells, and embryonic stem cells sites.
