Cell biology is a branch of biological sciences that investigates the structure, function, dynamics, and regulation of cells as the fundamental units of life. It encompasses the study of cellular organelles, membranes, cytoskeleton, intracellular trafficking, signal transduction, cell cycle control, cell division, differentiation, and cell death. Using approaches from molecular biology, biochemistry, genetics, microscopy, and biophysics, cell biology analyzes how macromolecular assemblies and biochemical networks give rise to cellular behaviors. It also examines cell–cell and cell–matrix interactions, and provides a mechanistic framework for understanding development, physiology, and pathologies such as cancer, neurodegeneration, and infectious diseases.
Prof. Dr. Elif Nur Fırat Karalar from Koç University's Department of Molecular Biology and Genetics and her team have uncovered the molecular mechanisms responsible for regulating a structure that plays a critical role in ...

A cell can act in astonishingly complex ways. It must decide for itself whether to grow and multiply, rest, specialize, age or die. This applies just as much to mammalian cells as it does to seemingly simple microbes.

Sexual size differences are widespread in biology, yet the "how" behind them often remains vague. We asked a concrete question in a classic model organism: when female flies are larger than males, do individual organs achieve ...
Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring cells stick together. ...

Our bodies are made up of countless cells, and each one is enclosed by a thin layer called the cell membrane. This membrane is not a rigid wall, but a soft, flexible sheet made of lipids. Beneath it lies a supportive network ...
