Our bodies are composed of many different types of cells that work together to build and maintain normal physiological functions. In the central nervous system, for example, neurons transmit information, while glial cells such as astrocytes regulate the environment surrounding neurons and support their function. Understanding how these cell types influence one another is essential for uncovering how our bodies develop and function.
