stem cell treatment

I just googled it and it seems stem cell therapy has been a reality for well over two decades.

Well, actually stem cell treatment is already in use. Bone marrow transplant is technically a type os stem cell therapy. Lets explain what is stem cell.

During the development of a new being, in the conception the two paternal gamets unite, i mean sperm and the ova. This combination creates a cell that is the most powerfull of an entire new human beeing it has the potential to create a whole body, with complete new tissues. This new cell starts dividing and the daughter cells start to specialize to create different type of tissue. There are cells that especialze in connective tissue, others in nervous system, others in internal organs. This cells are what we call stem cells. They can become specialized in an specific tissue according to a prestablished program on their dna or according to the media requirement.

Bone marrow transplnat takes healthy marrow cells that are capable of producing the whole range of types of red and white blood cells to replenish a recipient patient that lacks this capability.

The actual investigations on stem cells is guiding towards to try and rebiuld damaged tissue, or to create substitute cells that had failed or had been destroyed on a particular patient. A good example is Parkinson disease.

Parkinson disease is caused by the progressive and unstopable destructio nof a particular group of neurons in the substantia nigra, located on the brain stem. They produce a substance called dopamine. Current treatment objective is to provide the brainstem with more dopamine to try supply what is lacking. A stem cell therapy would add new healthy cells on the patients brain stem. Taking a few stem cells and forcing them (or guiding them) to transform into the type of neurons the patients needs.

If the investigations suceed in the future we can be even able to create new organs. Imagine harvesting a new liver for a patient with fulminant hederitary fibrosis of the liver. Or repair the brain stem of a child with paralysis.

A time of real miracles in medicine is about to come.
