Wnt signaling is a complex cell communication pathway that plays a crucial role in regulating various biological processes, including cell growth, differentiation, and embryonic development. It involves a series of proteins that transmit signals from the cell surface to the nucleus, influencing gene expression and cellular behavior. When Wnt proteins bind to their receptors on the cell surface, they initiate a cascade of events that can lead to changes in cell fate and tissue formation. This signaling pathway is essential for maintaining stem cell populations and is also implicated in various diseases, including cancer, when it becomes dysregulated.
