as the basis for the arteries used by human muscle cells stimulated to multiply. Then these cells incorporated the gene hTERT, which increases their life expectancy. Genetically modified cells are placed on the biopolymer tube, which in consequence of self-absorbed, and take its shape.
As the researchers say, two months later, the vessel is tight and suitable for transplantation. Thus the already established four arteries of 8 centimeters and a diameter of 3 millimeters.
gene hTERT, embedded in the muscle cells can cause cell division within the vessel after the implantation, due to which, before the introduction of new techniques, it is necessary to ensure its security. In addition, scientists will determine whether they are able to withstand the constant jumps artery blood pressure caused by cardiac muscle.
It says study leader Laura Niklason (Laura Niklason), the greatest need in these arteries arise, when they created artificial organs: the liver, lungs and kidneys. And now, when such bodies do not, except with coronary heart disease, the need to "test-tube" vessels are among those facing the amputation of limbs due to vascular disease.
