Differential cell death response to photodynamic therapy is dependent on dose and cell type

PDT-induced cell death. by either apoptosis or necrosis may vary with cell type or PDT dose. 5 cell types were treated with varying doses of aminolaevulinic acid-induced PDT and the type of cell death analysed. The mode of cell death was found to depend on both cell type and light dose. (C) 2001 Cancer Research Campaign.
