Stem cells are the clean slates of the human body. They're the cells (usually found in bone marrow) that are stored till they have a significant job. Stem cells remain stem cells until they need to differentiate into a specific type of cell i.e a heart cell, a kidney cell or even a skin cell. New research goes into the way stem cells differentiate and what goes into the process. The study (conducted by the Institute of Biotechnology and Massachusetts Institute of Technology (MIT)) suggests that asymmetric apportioning of old cellular components during cell division may represent an anti-aging mechanism utilized by stem cells. They focus on tissue stem cells, that continuously renew our tissues which divide asymmetrically to produce 2 types of daughter cells: one a new stem cell, the second one will become the differentiating cell of a tissue. Stem cells undergo this technique to prevent cellular damage. Extra damage can cause stem cell fatigue and less tissue regeneration an
