Cells are the fundamental unit of living organisms. Biologists have studied cells for centuries in order to understand their physiological properties, their structure, the organelles they harbour, interactions between cells and with their extracellular environment, their life cycle, how they divide and how they die.
Modern cell biologists use a multitude of techniques from whole organism microscopy rightdown to the molecular level investigating the proteins and the genetics of cellular components and cell functions. Cell biology research encompasses both the great diversity of single-celled organisms like bacteria and protozoa, as well as the myriad specialised cells in multicellular organisms such as humans and plants. Cell biology is at the core of developmental biology and stem cell research as well as immunology and cancer biology.
