The New Fountain of Youth: Adult Stem Cells

Youth is synonymous with health. So what is abundant in the young and the old poor? ¿Abundant cells operating at full capacity.?       The human being is made up of trillions of cells. The multiple cellular functions within the human body is possible thanks to cell specialization. Multitude of cell types, specialized somatic cells, cell functionality varied ensure that the human organism needs to live.       In youth, the stem cells are very abundant. Actively dividing to produce new daughter cells. The daughter cells grow and differentiate into somatic cells, specific according to their place of birth.The daughter cells occupy the empty spaces left by his sisters to death. This is the natural repair of the human body. It is a repair mechanism almost perfect author. But stem cells can not divide infinitely. They have a limited number of cell divisions described by Hayflick Index. When a stem cell spends its last cell division, it dies.      With the death of a stem cell, cell turnover decreases. The tissue aging because not renewed completely. As stem cells disappear, the fabric falls into organ failure, and the subject dies without being able to reach its maximum longevity. From the age of 25 gradually decreases cell turnover. Youth ends and begins aging skin
