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‑10b plays a critical role in maintaining mesenchymal stem cells and determining whether they differentiate to adipocytes or osteoblasts. Wnt-10b is mainly produced by stem cells and pre-osteoblasts, but also by adult bone marrow CD8+ T lymphocytes stimulated with parathyroid hormone. In some hepatocellular carcinomas, Wnt-10b can inhibit cancer cell growth, but in others, it can act synergistically with FGFs to stimulate cell growth. Several Wnts, including Wnt-10b, are expressed in both normal and/or malignant colon tissues.
