Cells and tissues: a microscopic world in action

Cells are fundamental building blocks of living organisms – the smallest units capable of independent function. Within cell interior, processes take place that determine the health of the entire organism. When cells join forces, they form specialized tissues, such as nervous or muscular tissue. Understanding the principles governing the behavior of individual cells and their collaboration within tissues is key to uncovering the secrets of health, regeneration, and organismal development.

Scientists at the Faculty of Biology UW, conduct research on the structure and function of cellular organelles such as mitochondria and chloroplasts, analyzing their roles in fundamental life processes, including the evolutionary perspective. They also study processes occurring within cells, such as the transport of substances between organelles, the functioning of the cytoskeleton (the intracellular scaffold), regulation of cell division, and apoptosis – the “suicidal” death of cells.

These studies that leverage advanced microscopic and molecular techniques are essential for understanding the adaptive abilities of organisms, disease processes, cancer, and regeneration. As a result, they often lead to discoveries with practical applications.
