Only one cell is needed Japanese biologists to grow cornea and other parts of the human eye.The results of a unique experiment professionals, University of Tokyo unveiled today at a symposium on reproductive medicine in the city of Yokohama.Scientists have used stem cells taken from the edge of the cornea.Such cells are able to develop into different tissues, performing functions in the body recovery.The selected cell was placed in a nutrient medium.A week later, she developed into a group of cells, and the fourth week was transformed into the cornea with a diameter of 2 cm in the same manner was obtained by including a thin protective layer (conjunctiva) covering the cornea from the outside.Scientists emphasize that the first full-fledged human tissues grown from a single cell.In addition, as a culture medium used synthetic chemical compounds, rather than the traditional in such cases, the substance taken from animals - such as calf serum or mouse bone cells.Organ transplantation, received a new way, eliminate the risk of transfer of infections from animals.It is reported that Japanese scientists plan to begin clinical trials soon after to make sure the safety of new technology.
