What is a stem cell?

Saturday, October 10th, 2009

Stem cells are the master cells of the human body.  They are simply the building block and foundation from which every organ and tissue in our body is formed. 

A stem cell is a cell that has the ability to duplicate itself endlessly and to become cells of virtually any organ and tissue of the body.  Healthy stem cells are able to repair or replace damaged tissue, therefore assisting with the reversal of disease and injuries, improving and maintaining optimal health. 

More recent technological advancements have enabled scientists to discover a great deal more about stem cells.  This recent research has generated a great deal of excitement as scientists have found adult stem cells in many more tissues than they once thought possible.  They have also realised stem cells can be stimulated and increased from the bone marrow.  It has also been realised that stem cells are linked to age. 

Stem cells have the remarkable potential to develop into many different cell types in the body. They can theoretically divide without limit to replenish other cells as long as a person is still alive.  When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialised function, such as a muscle cell, a red blood cell, or a brain cell. 

By enabling more stem cells into the blood stream people will not age as quickly, will sustain growth and well being for a much longer period of time and will fight disease much more effectively and aggressively.  This new found technology is providing hope to millions of people of all ages, whether they are already fit and healthy and wanting to maintain optimal levels of health and well being or if they have a degenerative disease that requires improvement, stabilisation and hope.

(the difference between adult and embryonic stem cells)

When the sperm fertilises the egg the first creation is a stem cell.  It then divides into more stem cells which continue to divide until they begin to differentiate (or change), becoming specific types of cells that will go on to form all of the different parts of the body.  

Adult stem cells are not embryonic stem cells. Embryonic stem cells are pre-birth and are the focus of much media attention. All stem cells in our bodies after birth are defined as adult stem cells therefore children also have adult stem cells. 

The use of adult stem cells in research and therapy is not as controversial as embryonic stem cells, because the production of adult stem cells does not require the destruction of an embryo. Additionally, because adult stem cells can be obtained from the intended recipient, (i.e. an autograft, stem cell enhancers and recipient transplants) the risk of rejection is essentially non-existent in these situations. Consequently, more US government funding is being provided for adult stem cell research. 

Adult stem cells are undifferentiated cells, found throughout the body after embryonic development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. They are also known as somatic stem cells (from Greek Σωματικóς, meaning of the body). 

Scientific interest in adult stem cells has centered on their ability to divide or self-renew indefinitely, and generate all the cell types of the organ from which they originate, potentially regenerating the entire organ from a few cells. 

Given their unique regenerative abilities, stem cells offer new potential for maintaining good health, keeping ageing at bay, and treating many diseases such as parkinson’s disease, diabetes, stroke, heart disease, multiple sclerosis, spinal cord injuries, alzheimer’s disease, muscular dystrophy and degeneration, arthritis, arthrosis, epilepsy, erectile dysfunction, lou gehrig’s disease, liver disease, neuropathy and much more.
