IWP-2 is widely used in biological research to inhibit Wnt signaling pathways, which are crucial for various cellular processes. It is particularly valuable in studying stem cell differentiation and tissue regeneration. Researchers utilize IWP-2 to block the secretion of Wnt proteins, enabling them to investigate the role of Wnt signaling in development, cancer progression, and other diseases. Additionally, it is employed in organoid cultures to control cell fate decisions, providing insights into tissue engineering and regenerative medicine. Its specificity makes it a key tool in understanding the molecular mechanisms underlying Wnt-related pathways.
