Wnt compositions and therapeutic uses of such compositions

摘要

The invention provides novel Wnt polypeptides that have improved production characteristics, solubility, systemic delivery, and tissue uptake, and polynucleotides encoding the Wnt polypeptides of the invention. The Wnt polypeptides of the invention can be used therapeutically, such as, for example, in methods of preventing or treating muscle loss and/or promoting muscle hypertrophy and growth.
