The results of the study will allow to make first steps in this direction.
Chromosome, which develops down syndrome, managed to remove from the cell, said researchers from the University of Washington.
It is known that every human cell is 23 pairs of chromosomes. If instead the pair in the 21st chromosome appears three identical chromosomes (trisomy), man is born with down syndrome.
In the new experiment, microbiologists have successfully corrected trisomy of the 21st chromosome in lab-grown human cells. They were able to completely remove the extra chromosome.
Experts said that before the creation of the methods of treatment of down’s syndrome but the results of the study will allow to make first steps in this direction.
