Stem cell is a kind of multi-potential with self-replication ability cells. Under certain conditions, it can differentiate into a variety of functional cells.
The best treatment of disease caused by genetic and genetic mutations is correcting the pathogenicity of the gene. Gene editing is a genetic manipulation of genomic specific sites. In recent years, new generation of gene editing technologies such as zinc finger nuclease (ZFN), transcriptional activator-like effector nuclease (TALEN) and Clustered regularly interspaced short palindromic repeats (CRISPR) have been developed rapidly, making it quickly targeted genetic modification is possible
