A new method of obtaining stem cells

July 3 2008

Scientists from the U.S. and Switzerland, conducted a series of experiments, which indicate the possibility of creating a new way to transform ordinary body cells into stem cells.

It is known that the human body is largely composed of epithelial tissue. It serves as a major component of many glands, covers the outer surface of the body and it lines the hollow organs, except blood and lymph vessels. Epithelial cells are able to transform into cells of another type, called mesenchymal. Members of the Institute of Biomedical Studies. Whitehead in the USA have discovered that mesenchymal cells of epithelial origin have many properties of stem cells exist in adult organisms. This finding should not from any theoretical models and therefore was quite unexpected.

Its authors did not exclude the possibility that their discovery could lead to new technologies of artificial obtain stem cells of various types. To block has undergone epithelial-mesenchymal transition, some of its genes must be deactivated, while others, on the contrary, begin to operate in enhanced mode, transmits
