How Do Cellular Signals Influence Regulatory Functions?
Cellular signals play a pivotal role in regulating tissue function. These signals include hormones, growth factors, and neurotransmitters. They bind to specific receptors on the cell surface or within cells, triggering intracellular pathways that control gene expression, protein synthesis, and other cellular activities. For instance, growth factors such as epidermal growth factor (EGF) can stimulate cell proliferation and differentiation, which are crucial for tissue repair and regeneration.
