Cell Division, Cytotoxicity, and the Assays Used in the Detection of Cytotoxicity
Cell division is a phenomenon that is encountered in all cells in nature. While normal cell division results in proliferation in single-celled organisms, and development and repair in multicellular organisms, aberrant and untimely cell division results in tumor formation. Therefore, the understanding of the cell division is hidden in identifying the details of the molecular mechanisms that govern cellular division at the exact time and under right conditions. Sometimes these molecular mechanisms are distorted by both intrinsic and extracellular factors, and the division process halts or deviates to an abnormal pathway. At this point, it is essential that the abnormal cells are removed from the tissue by an appropriate mechanism. In this context, in this review, general and specific information about cell division and its molecular control mechanisms were discussed, and different types of cell death mechanisms were mentioned accordingly. In addition, chemical, biological, and physical cytotoxic agents that negatively affect cell division and their mechanisms of action are explained. Finally, a brief review of the principles of different cytotoxicity (cell viability and proliferation) test systems has been performed to provide a source of information for investigators who study cell viability, proliferation, or different types of cellular death pathways.
