In multicellular animals, cells communicate by emitting and receiving proteins, a process called signaling. One of the most common signaling pathways is the transforming growth factor b (Tgf-b) pathway, which functions in all animal species throughout their lifetimes and regulates numerous biological processes, such as instructing cells how to differentiate—whether a stem cell will become a muscle cell or a bone cell, for example.
