Cell biology is the study of processes carried out by individual cells such as cell division, organelle inheritance and biogenesis, signal transduction and motility. These processes are often affected by stimuli from the environment including nutrients, growth signals, and cell-cell contact. Single-celled organisms such as yeast, multicellular organisms such as Drosophila and mouse, established tissue culture lines, and, increasingly, primary cell cultures derived from recombinant animals such as mice are commonly used to study cell biological problems. Experimental approaches to the study of cell biological problems include genetics, microscopy, and reconstitution of cell biological events in cell-free systems.
