Brain grown from stem cells
Austrian scientists for the first time, the world has grown from stem cells in the human brain is small. The results of the research are published in the journal Nature. To grow a brain, biologists took skin cells healthy person and reprogrammed them into stem cells (iPSC, induced pluripotent stem cells), which can develop into any type of tissue. The thus obtained stem cells are first grown in a special gel substrate, the structure resembling the connective tissue of the human body, and then placed in a tray. After a while of stem cells grown some structures resembling embryonic brain during the ninth week of development. The diameter of each reached 3-4 mm. Under the microscope, the scientists were able to examine the interacting region of the brain. In the mini-brain was detected even bark. "The overall structure of the grown samples differed," - said Noblich. This is due to the fact that in normal fetal brain maturation run molecule growth factors produced elsewhe...
