Cell signaling in development

Cell signaling in development involves how cells communicate to coordinate growth and formation of tissues and organs. Cells send and receive molecular signals, like proteins or hormones, that trigger specific responses—such as dividing, differentiating into specialized cells, or migrating. This communication ensures that cells develop in the right place, at the right time, and in the correct quantity, guiding the complex architecture of a developing organism. Proper signaling is essential for normal development, while errors can lead to developmental disorders or diseases.
