TitleGeneration of genetically modified non-human primate and its application

Time: August 9 (Friday) 2017, 3:00pm

Venue: Laboratory of Southwestern Biodiversity, 1st floor conference room (1-24-26)

Everyone is welcome! 

Genetically modified (GM) animals represent a crucial tool for understanding gene function in development and disease. The type II bacterial CRISPR/Cas system has been demonstrated as an efficient gene-targeting technology to generate mice carrying mutations and reporter. However, GM animals generated by CRISPR/Cas9 system are mosaicism, in which two or more populations of cells with different genomes are present in an individual animal. It is costly and time consuming to produce single-gene knockout animal and even more so to make double-mutant animal through the germline transmission of chimeric animals, especially for non-human primate, due to its longer sexual maturity lengths (4 to 5years) as compared to rodents. Here we optimized CRISPR/Cas9 system and obtained fully functional knockout mice for one gene or multiple genes in one step. Using this optimized CRISPR/Cas9 system, we did high-throughput screen for genes located on mouse Y chromosome. Finally, we obtain fully functional knockout monkey at first generation by this method.
