What is it about?

Avian genome editing has relied on utilization of primordial germ cells (PGCs) to generate genome-edited offspring in the next generation. In this study, we provide a new method for genome editing in different avian species. We showed that the injection of adenovirus containing the CRISPR/Cas9 system into blastoderms of freshly laid eggs can induce genome editing in the blastodermal PGCs and generate genome-edited chicken and duck offspring.

Why is it important?

The adenovirus-mediated method could allow more researchers to conduct genome editing in various avian species, thereby accelerating the avian genome editing-related research, and providing potential benefits to the agricultural industry.
