Genetics and epigenetics of stem cells

During last five years stem cells and cellular based technologies were thrice awarded by Nobel committee although they are not widely used in clinical practice yet now. There are a number of unresolved issues concerning stem cells genetic stability, differential potential and self-renewal. We are working with two types of human pluripotent stem cells: embryonic (ESC) and induced pluripotent stem cells (iPSC). We have established a number of ESC lines and used them to study epigenetic characteristics of pluripotency maintenance (Lagarkova et al., 2006) and genetic stability during long term cultivation (International Stem Cell Initiative et al., 2011). We have also developed robust protocols of human pluripotent stem cells differentiation into the cells of retina pigmented epithelium, endothelial cells, cardiomyocites etc (Lagarkova et al., 2008, Lagarkova et at., 2011). Utilizing reprogramming approaches we generated a number of iPSC lines and characterized their epigenetic profiles during reprogramming (Shutova et al., 2009, Lagarkova et al., 2010). iPSC generated from patients with genetically determined disorders such as Parkinson and Huntington diseases, amyotrophic lateral sclerosis, macula degeneration, myodistrophy and some others are currently under investigation to establish pathology mechanisms and to develop new treatments.
