Stem cell research is considered one of the most captivating areas of cell biology mainly due to the unique properties of stem cells and their potential use in cell-based therapies to treat a variety of diseases, including Parkinson's disease (PD), Alzheimer's diseases (AD), Diabetes Mellitus (DM), and many others (Correia et al., 2005; Pagliuca et al., 2014; Sproul, 2015). Given their unique regenerative abilities, these cells provide new potentials in the area of regenerative or reparative medicine.
