AVS Bio - mRSPO1-Fc

The Wnt signaling pathway is essential for embryonic development, stem cell differentiation and regeneration of injured tissues. Wnts hetero-dimerize Frizzled (Fzd) family receptors and their co-receptors Lrp5/6, triggering downstream signaling pathways including the canonical β-catenin cascade, and resulting in expression of genes regulating cell development. R-Spondins regulate Wnt/ beta -catenin by competing with the Wnt antagonist DKK-1 for binding to the Wnt co-receptors LRP-6 and Kremen, reducing their DKK-1-mediated. RSPO3-Fc Fusion-protein supports long-term expansion of multiple different types of organoids, including pancreas, stomach, colon and liver organoids.
