chinese scientists produced the world's first genetically-engineered human blood 2 cells, providing a 3 option for 4 use.
中国科学家制造出世界第一个基因工程人类血管细胞，为相关治疗带来了希望。
the study published on thursday in the journal cell stem cell showed that human
5 cell function can be enhanced by editing a single longevity-related
1.
scientists from the institute of biophysics of the chinese academy of sciences (cas), peking university and the institute of
6 of cas targeted a gene called foxo3, an important regulator to delay
7 aging, resist stresses and enhance cardiovascular balance.
the technique can also resist the cells'
8 into tumors. the risk of
9 transformation used to be a major concern for the application of the gene-editing technology.
the researchers tested it in a mouse model with blood-shortage or ischemic injury and found that those cells promoted vascular regeneration and resisted tumor transformation both in vitro and in vivo.
they expected to use gene-editing strategies in the future to produce high-quality, safe human vascular cell
10 in a large-scale and
11 manner.
