Recent advances in the study of the CRISPR/Cas9 system have provided a precise
and versatile approach for genome editing in various species. However, the
applicability and efficiency of this method in large animal models, such as the
goat, have not been extensively studied. Here, by co-injection of one-cell stage
embryos with Cas9?mRNA and sgRNAs targeting two functional genes (MSTN and FGF5),
we successfully produced gene-modified goats with either one or both genes
disrupted. The targeting efficiency of MSTN and FGF5 in cultured primary
fibroblasts was as high as 60%, while the efficiency of disrupting MSTN and FGF5
in 98 tested animals was 15% and 21% respectively, and 10% for double gene
modifications. The on- and off-target mutations of the target genes in
fibroblasts, as well as in somatic tissues and testis of founder and dead
animals, were carefully analyzed. The results showed that simultaneous editing of
several sites was achieved in large animals, demonstrating that the CRISPR/Cas9
system has the potential to become a robust and efficient gene engineering tool
in farm animals, and therefore will be critically important and applicable for
breeding.
