Glossary2D cell culture

cells grown on flat surfaces for research purposes

2D cell culture, also known as two-dimensional cell culture, is a laboratory technique where cells are grown on a flat, typically plastic, surface such as a petri dish. This method allows researchers to study cell behavior, drug responses, and biological processes in a controlled environment, but it may not fully replicate the complex interactions found in a living organism.
