Stability of cell lines which are used in every applicative field is mandatory; cell lines in fact must maintain their unique features (whether original or acquired) along time, under definite cultivation conditions. For this reason, when a new cell line is developed harbouring the desired features, a single clone is selected and propagated, to constitute the Master Cell Bank (MCB). Starting from MCB, a Working Cell Bank (WCB) is subsequently developed, which is used in further applications.
