Used in research to enhance Wnt signaling pathway activity, particularly in stem cell cultures where it supports the growth and maintenance of intestinal, hepatic, and other epithelial organoids. Facilitates studies on tissue regeneration, developmental biology, and disease modeling by promoting cell proliferation and differentiation. Commonly applied in in vitro assays to investigate receptor-ligand interactions involving LGR4/5/6 and to screen potential therapeutic compounds targeting Wnt-related pathways.
