ABSTRACT

Peripheral blood lymphocytes as primary cells can be isolated from human, animal, fetus, and placenta. These cells are an excellent cellular model for the assessment of cytotoxicity, genotoxicity, oxidative stress, and mitochondrial and lysosomal dysfunction induced by drug and chemicals. Moreover, peripheral blood lymphocytes are an easily available source of primary cells appropriate for basic research and in cellular studies regarding teratogenic, genotoxic, and cytotoxic effect of drugs and chemicals. Most drugs and other chemicals that produce birth defects, known as teratogenic agents, produce reactive oxygen species (ROS) formation and mitochondrial and lysosomal dysfunction. It seems that there is an important mechanistic link between oxidative stress, mitochondrial damages, lysosomal integrity, and teratogenic drug-induced birth defects. One of the most sensitive periods in the embryo is transition from an important developmental event to another such as transition from proliferation to differentiation. Mitochondria, lysosomes, and cellular ROS have an important role in proliferative, differentiative, and apoptotic activities during the development. Therefore, disruption of the function of mitochondria, lysosomes, oxidative stress, and redox imbalance leads to cellular dysfunctions and subsequently poor developmental outcomes in the fetus. In this chapter, we will focus on evaluation of mitochondrial/lysosomal functions and estimation of ROS formation using flow cytometry methods in isolated lymphocytes and their isolated mitochondria.
