For in vivo applications to address genetic diseases, we deploy CRISPR/Cas9 as the therapy that targets cells within the body. In parallel, we are developing ex vivo applications to address immuno-oncology and autoimmune diseases, where we use CRISPR/Cas9 as the tool to create the engineered cell therapy.
Our in vivo programs use CRISPR to enable precise editing of disease-causing genes directly inside the human body. In addition, we are advancing ex vivo applications to address immuno-oncology and autoimmune diseases, where we use CRISPR/Cas9 as the tool to create the engineered cell therapy. For our ex vivo programs, CRISPR/Cas9 is used to engineer human cells outside the body.
