What is the relationship between stem cells and aging? How do we slow down or reverse the visible signs of aging? How do we prevent us from getting wrinkles and aging diseases?

Stem cells

To be able to understand about the anti aging stem cell therapy, we need to discuss first the stem cells. Stem cell science provides a new concept for treating aging and diseases brought by aging. The stem cell is perceived as the origin of life. All cells came from cells. For adults, stem cells proliferation triggers tissue renewal. The process starts with a cell dividing itself to form a new cell (Sell, 2004). One portion remains as the original stem cell while the other undergoes differentiation to perform the function of the mature cell type.

How do we understand aging? Aging is a process of organ function decline and tissue degeneration associated with increased oxidative damage, endocrine imbalance, mitochondrial dysfunction, and genomic instability (Clayton & Rowbotham, 2009). Aging is one form of response of the organ?s regenerative capacity. Every organ and tissue that we have is made up of stem cells.

Can we rejuvenate stem cells by exposing them to a young systemic environment?

An experiment performed between young and old mice demonstrated that the stem cells of the young mice were able to influence to and aid the bone marrow regeneration of the old mice (Clayton & Rowbotham, 2009). The outcome of the study showed that aging could be reversed by modulation of systemic factors. Treating diseases with stem cells is not a new concept. Actually, blood disorders, blood cancers, and immune system disorders were using adult stem cells for treatment over half a century for now. They became routine medical procedures for curative protocols.

One of the biggest questions is when do stem cells know when to stop reproducing themselves and start producing specialized cells for the targeted tissue. The stem cell has the ability to divide into a progenitor cell that tends to create the specialized cells. In most cases, researchers believed that stem cells receive their signals from proteins and other controlling molecules responsible for directing cell specialization (Goldstein & Schneider, 2010). In the past years, some proteins were identified as controlling proteins that tell stem cells to generate new skin cells.

Umbilical and placental cells

There has been an increasing interest on the use of stem cells taken from the human placenta or umbilical cord. This provides younger stem cells that can be banked first at birth for later use in stem cell treatments (Giampapa & Williamson, 2004)). Umbilical stem cells contain progenitor cells. Progenitor cells can mirror the stem cells found in the bone marrow. This is a good way to gather stem cells because it clears any ethical concerns about the origin and perfect matching of immune characteristics. In many cases, the umbilical stem cells were infused by bone marrow ablation through chemotherapy or radiation to cure cancer or leukemia. Eventually, the traditional treatment for visible effects of aging will be replaced by stem cells actual tissue replacements.

Mitochondria theory

This process might help validate the theory about mitochondria as the key player in the human?s aging process. It has been speculated in the past that aging was the result of the loss of capacity of the human body to repair mitochondrial and nuclear DNA (Giampapa & Williamson, 2004)). If this theory is correct, then aging may be reversed by introducing new virgin mitochondria into the aging body. If this theory is correct, then stem cells transplant can promote production of ATP and improve the biomarkers of aging.

Organ repair

Advanced stem cell therapy can repair organ systems that were impaired with the process of aging. Stem cell treatment for the central nervous system can alleviate mental deterioration, Alzheimer?s disease, and any age related memory impairment (Giampapa & Williamson, 2004)).

Nanotechnology

The nanotechnology utilizes molecules to act as machine and perform task that may not be possible in other known ways. This could be possibly use for the repairs of arteries, veins, and capillaries. Nanotechnology may provide a gateway to the remodelling or genetic repair (Giampapa & Williamson, 2004)). Years from now organ specific anti aging therapy may be available to improve human quality of life. It is very possible to directly manipulate genetic sequences of human beings, which has already started with the DNA manipulation and replication.
