Mesenchymal stem cells (MSCs) have emerged as an attractive candidate for cell-based therapy. In the past decade, many animal and pilot clinical studies have demonstrated that MSCs are therapeutically beneficial for the treatment of obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, due to the scarcity of adult human MSCs, human-induced pluripotent stem cells mesenchymal stem cells (iPSCs) are now increasingly used as a source of MSCs. iPSCs are derived by reprogramming somatic cells from a wide variety of tissues such as skin biopsies and then differentiating them into iPSC-MSCs. One of the mechanisms through which MSCs exert their protective effects is mitochondrial transfer. Specifically, transfer of mitochondria from iPSC-MSCs to lung cells was shown to protect lung cells against oxidative stress-induced mitochondrial dysfunction and apoptosis and to reduce lung injury and inflammation in in vivo models of lung disease. In this chapter, we detail our methods to visualize and quantify iPSC-MSC-mediated mitochondrial transfer and to study its effects on oxidant-induced airway epithelial and smooth muscle cell models of acute airway cell injury.
