Skin cells for treatment of anemia


The team of scientists in the United States to find out how to fight the disease known as "cell anemia" by the use of skin cells.

This type of anemia is hereditary disease affects the ability of red blood cells to transport oxygen to the rest of the body and can cause pain and damage to body tissues.

Adopt new method, as described in the scientific journal (Science), for reprogramming skin cells into cells essential to (stem).

The scientific team used cells produced by the treatment of human type mice suffered from the disease.

Such a method to make treatment available to patients constantly, as well as develop a solution to the ethical objections to the use of other sources for stem cells, such as embryos.

But experts believe that it is necessary to conduct further tests to ensure that these cells are well-suited for medical treatment, before moving to the stage of testing on humans.

Stem cells
It is noteworthy that the stem cells are the first cells in the early embryonic stages of development and the advantage of its ability to switch to different forms of cells that are living tissues and organs, making them suitable for the treatment of a broad spectrum of diseases.

Scientists believe that the most benefit those stem cells taken from embryo tissue, the ability to develop all types of cells in the body approximately.

There are also stem cells in the body, including skin deep.

While stem cells derived from the skin to stimulate cells have the capacity promising therapeutic use, but scientists warned of the possibility that the symptoms caused serious side.

The main method of production of these cells that scientists took skin cells from the mice sick and then using viruses of the type of "Retro" to introduce genes (genes) to the therapeutic DNA (De any) of these cells.

Warnings
Although this method as an effective therapeutic to a large degree, but the viruses ability to random changes in DNA in other parts of the body, which may lead to a satisfactory cancer for example.

He says Rudolph Jenich, a prominent researcher at the Whitehead Institute for biomedical research in Massachusetts, United States, the need to find cures for "not interfere with the genome (ie the total genes organism).

He explains that viruses "Retro" could "either hinder certain genes should not obstruct or active genes should not be revitalized."

The great Sourani Professor of the University of Cambridge says that this "important step forward, but in addition to fears over safety conditions us to beware of excessive application of the studies used rats to humans."

He believes that the stem cells derived from the skin to stimulate cells of mice is not identical to the corresponding human beings at which requires further research, there are important obstacles to overcome. "

The estimated number of sufferers cell anemia in Britain about 12500 people
