Americans have found a way to restore nerve tissues
Researchers from Medical School of Pennsylvania University have shown that human neurons can be used to create the three-dimensional networks with a set topology, suitable for transplantation on a place of the damaged nerve tissues.
Earlier scientists have managed to grow in a nutrient medium rats’ network of neurons from back-radicular ganglions. In the new work they have created a similar network from human neurons.
Scientists isolated nerve cells from back-radicular ganglions and thoracal neurons. Cells have been cleared and raised in a nutrient solution, stimulating growth of axons by a mechanical tension. Axons grew approximately 1 millimeter a day, and in general neurons have been cultivated for about 3 months, keeping their ability to transmit nerve impulses.
