Ageing is a complex process that varies as to how it affects different people and even different organs. Most gerontologists (people who study ageing) feel that ageing is due to the interaction of many lifelong influences. These influences include heredity, environment, culture, diet, exercise and leisure, past illnesses, and many other factors.
Unlike the changes of adolescence, which are predictable to within a few years, each person ages at a unique rate. Some systems begin ageing as early as age 30. Other ageing processes are not common until much later in life.
EFFECT OF AGEING ON STEM CELLS
Stem cells are a class of undifferentiated cells with a remarkable potential to develop into different cell types such as skin, muscle, bones etc. With their unique regenerative abilities, stem cells serve as a type of internal repair system in many tissues, dividing essentially without limit to replenish or replace other cells that are lost through normal wear and tear, injury or disease.
According to report there is now compelling evidence that the ageing process has a deleterious effect on stem cells, and that the ageing effects on stem cells may have play essential roles in the pathophysiology of the various ageing-associated diseases.
DISEASES OF AGEING FROM OLD STEM CELLS
Adult stem cells, also known as somatic stem cells, are found throughout the body in every tissues and organs after development and function as self-renewing cell pools to replenish dying cells and regenerate damaged tissues throughout life. However, adult stem cells appear to age with the person.
As stem cells age, their functional ability also deteriorates. Specifically, this regenerative power appears to decline with age, as injuries in older individuals heal more slowly than in childhood. For example, healing of a fractured bone takes much longer time in elderly than in young individuals.
There is a substantial amount of evidence showing that deterioration of adult stem cells in the adult phase can become an important player in the initiation of several diseases in ageing.
WHAT IS CELL THERAPY?
Stem cell therapy as an anti ageing treatment helps to increase the levels of stem cells circulating through the bloodstream. The goal of cell therapy as a regenerative medicine is to stimulate cell rejuvenation and regeneration, thereby slowing down the natural process of ageing and counteracting chronic diseases.
