Regenerative Stem Cells

Stem Cell Science

We have trillions of cells in our body that all take different amounts of time to renew. Whether it’s shedding skin or growing new hairs, the human body is in constant flux. Remarkably, approximately 330 billion cells get replaced every day of our lives. This is equivalent to about 1 percent of all our cells.

Most people have heard the adage that our bodies renew themselves in 7 to 10 years. Researchers confirm the average age of all cells in the human body is indeed seven to 10 years. However, it doesn’t mean we have a whole new body every decade as cell renewal happens at different rates. Cells in our colon, for instance, are replaced every three to five days, but our muscle and fat cells can take up to 70 years to renew.

The Liver Must Renew Itself To Remain Immune To Damage

The liver must renew itself every 150 to 500 days to remain immune to damage from toxins whereas skin cells, given it is the body’s outermost layer of protection, must regenerate every two to four weeks. The cells that line the surface of the stomach have one of the shortest time spans as they are constantly battered by corrosive stomach acids. These cells typically last no more than five days.

Here’s the challenge, our cell renewal process slows down with age. When it comes to cell renewal, the secret lies in our bone marrow. Depending on where the stem cells are, they can develop into different tissues. For example, hematopoietic stem cells reside in the bone marrow and can produce all the cells that function in the blood.

Stem cells also can become brain cells, heart muscle cells, bone cells or other cell types. This is where we store the solution to cell renewal in the form of adult stem cells. Stem cells have the remarkable ability to renew themselves and can develop into many different types of cells in the body.

Our Healing Depends On The Number Of Stem Cells Available

Our ability to heal and renew is in direct proportion to the number of adult stem cells we have available. The problem is, as we age, we release fewer and fewer stem cells. We have a natural solution that increases our ability to release these cells into our body by 34% every 12 hours, enabling us to replace dead and dying cells, literally prolonging life.

People who might benefit from stem cell therapies include those with leukemia, Hodgkin disease, non-Hodgkin lymphoma and some solid tumor cancers. Stem cell therapies also might benefit people who have aplastic anemia, immunodeficiencies and inherited conditions of metabolism.

Stem cells are being studied to treat type 1 diabetes, Parkinson’s disease, amyotrophic lateral sclerosis, heart failure, osteoarthritis and other conditions.

Stem cells may have the potential to be grown to become new tissue for use in transplant and regenerative medicine. Researchers continue to advance the knowledge on stem cells and their applications in transplant and regenerative medicine.
