1. What is a stem cell?
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. Embryonic stem cells are cells extracted from the blastula, the very early embryo, that have an exceptional ability to duplicate in vitro, that is in a test tube, and to become cells of almost any tissue. Adult stem cells are cells found in an organism after birth. Until very recently, it was believed that adult stem cells could only become blood cells, bone and connective tissue. But recent development over the past 5 years have revealed that adult stem cells have capabilities similar to embryonic stem cells.
2. What is the Stem Cell Theory of Renewal?
The Stem Cell Theory of Renewal proposes that stem cells are naturally released by the bone marrow and travel via the bloodstream toward tissues to promote the body’s natural process of renewal. When an organ is subjected to a process that requires renewal, such as the natural aging process, this organ releases compounds that trigger the release of stem cells from the bone marrow. The organ also releases compounds that attracts stem cells to this organ. The released stem cells then follow the concentration gradient of these compounds and leave the blood circulation to migrate to the organ where they proliferate and differentiate into cells of this organ, supporting the natural process of renewal.
3. Why do we hear much in the news about embryonic stem cells and very little about adult
The first human embryonic stem cells were grown in vitro, in a petri dish, in the mid 1990s. Rapidly, scientists were successful at growing them for many generations and to trigger their differentiation into virtually any kind of cells, i.e. brain cells, heart cells, liver cells, bone cells, pancreatic cells, etc. When scientists tried growing adult stem cells, the endeavor was met with less success, as adult stem cells were difficult to grow in vitro for more than a few generations. This led to the idea that embryonic stem cells have more potential than adult stem cells. In addition, the ethical concerns linked to the use of embryonic stem cells have led to a disproportionate representation of embryonic stem cells in the media.
But recent developments over the past 2-3 years have established that adult stem cells have capabilities comparable to embryonic stem cells in the human body . not in the test tube. Many studies have indicated that simply releasing stem cells from the bone marrow can help support the body’s natural process for renewal of tissues and organs.
4. What is the effect of StemEnhance ® ?
StemEnhance ® is a blend of two compounds extracted from the widely consumed aquatic botanical Aphanizomenon flos-aquae (AFA). One extract, which contains an L-selectin ligand, supports the natural release of stem cells (CD34+ cells) from the bone marrow. The other extract, a polysaccharide-rich fraction named Migratose™, may support the migration of stem cells out of the blood into tissues.
