Cells are the smallest units of life, providing structure and function for all living things, from microorganisms—like bacteria, algae, and yeast—to humans. They come in a wide range of sizes and shapes, and they’re complex machines with many smaller components that work together.
Some NIGMS-funded researchers use imaging techniques to peer inside cells, examine their structures, and study how they divide, grow, communicate, and carry out basic functions. Others use biochemical and genetic tests to study how cells interact with their environments, including those that may be toxic. Understanding cells’ biological processes helps to keep us healthy and identify new methods for treating disease.
