Cell culture systems are essential tools used in a wide range of biomedical and clinical studies. Two dimensional cell culture models (2D) provide basic information on cytotoxicity, penetration and accumulation of drugs in cells and they are of outmost importance when selecting new compounds of the desired biopharmaceutical properties as candidates for novel drugs. The improvement over 2D growing cells are three dimensional (3D) tissue models that mimic in vivo conditions and the functions of living tissue more accurately. These models reduce the cost of drug development, enable more efficient drug screening, minimise failure rate in medicine discovery and eliminate animal use during experiments. The article provides an overview of 2D cell cultures and 3D tissue models - their properties, basic procedures, conditions of culturing and applications.
Keywords: 3D tissue model; Cell culture; Cytotoxicity; Drug discovery; Permeability.
