Resemble skin cells to neurons !!!

This problem could be associated with certain types of diseases originating in the thyroid gland, by heart disease and infertility in men and problems in the immune response.

Researchers at the School of Medicine, Stanford University were able to set up the skin cells behave like neurons.

The work was accomplished through the manipulation of the process by which DNA transfers information from the skin cells in the fetus, so the newspaper said the BBC.

The scientists worked with a genetically modified virus to which were added four proteins also known as transcription factors in fetal cells of the skin.

When introduced transfer factors found that the compounds became a small portion of skin cells into cells that reacted neurons.

This technique had AIDS tested and used in mice, and now could help in the investigation of neurological diseases, the researchers wrote in the journal Nature.

Marius Wernig, director of research, said the discovery is unique because it was known that a cell could become specialized cell, but not a cell could transform into another cell type.

Considers that this development will serve to create disease models in which a patient's cells to help counter the effects of neurological disease.

Compared to other studies this process did not require reprogramming of cells to become mothers if not directly in neurons for a month.
