Mitochondrial DNA Mutations Seen to Rise with Age and Hamper Effectiveness of Stem Cell Therapies
The benefits of induced pluripotent stem (iPS) cells, generated from patient-derived skin samples and used to repair damaged tissue, may be hampered by age-related mutations in mitochondrial DNA, a new study reported. The study argues for careful screening of mitochondrial DNA mutations in these cells. Patient-derived stem cells, obtained through a…
