Sana Biotechnology focuses on healthcare innovations, particularly in gene and cell therapy. They are working on advanced techniques to modify genes and cells for treating various diseases. This involves two main strategies: ex vivo (outside the body) and in vivo (inside the body). For ex vivo, they aim to engineer cells like CAR T cells for cancer, and for in vivo, their goal is to directly modify genes within the body to treat genetic diseases. Their efforts also include overcoming challenges such as immune rejection and ensuring the effectiveness of these therapies.
