Many clinics offer cell treatment, and their claims concerning what stem cells can or can not do are not proven by people’s understanding of science sometimes. Before exposing yourself to treatment with the use of stem cells, we need to know the following:
There exist many types of stem cells, whereas each type is to serve its own aim. The types of stem cells are taken from many different parts of people’s body. The cells appear at different times of people’s lives either. There exist, for instance, embryonic stem cells (they exist at the very earliest developmental stages only) and specific types of cells that are called tissue-specific (or “adult”) stem cells. The latter appear during people’s after-birth development to remain throughout people’s lives. Tissue-specific cells are potential-limited and become the cell types that are to be found in the body tissue which they have been previously derived from.
A single stem cell therapy never works on multiple and unrelated diseases and conditions. Every type of cells in question has a specific function in people’s body and is never expected to make other tissues’ cell types. That is why unrelated conditions are not treated with a single cell type. The only exception is embryonic stem cells that are used to produce treatment for an extremely wide range of diseases/conditions. Though, embryonic stem cells may not be used for therapies just as they are, as they may to cause tumor and cannot become the cells that are necessary to independently regenerate some tissues. Embryonic stem cells have to be processed first to further develop into a specific cell type prior to transplantation.
Nowadays, there are only very few accepted therapies with the use of stem cells. The number of the conditions/diseases that might be cured this way is extremely restricted. The most extensively used method is blood stem cell transplantation that is done to treat diseases of the blood and immune systems.
