Wnt is a group of proteins that play a crucial role in cell signaling, which is how cells communicate with each other. These proteins are involved in various biological processes, including cell growth, differentiation, and movement. The Wnt signaling pathway is essential for embryonic development and helps regulate the formation of tissues and organs. In addition to development, Wnt signaling is important in adult organisms for maintaining tissue homeostasis and repairing injuries. Abnormal Wnt signaling has been linked to several diseases, including cancer, making it a significant area of research in understanding and treating various health conditions.
