Gene Therapy: Embryonic Engineering and the Future of Human Evolution

Welcome to Part 3 of my series on gene therapy and genetic engineering. If you haven’t already, I’d suggest reading Parts 1 and 2 before you continue: Introduction to Gene Therapy: It Sounds Simple, But It’s Sure Not Easy Gene Therapy: Vectors, Viruses, and Why CRISPR Will Change Everything Today, we’re talking about the second major challenge with gene therapy – getting replacement DNA into EVERY affected cell in a patient’s body – and why that problem leads to the central ethical debate in this field. Who Are the Patients? Gene therapy is designed for patients with genetic diseases....

Gene Therapy: Vectors, Viruses, and Why CRISPR Will Change Everything

Welcome to Part 2 of my series on gene therapy! If you haven’t already, I recommend that you read Part 1, Introduction to Gene Therapy: It Sounds Simple, But It’s Sure Not Easy, before continuing with this post. Ready? Here we go. Viruses: FedEx For Genes Gene therapy involves repairing or replacing a faulty gene that has led to disease. In order to do that, one major hurdle must be overcome: getting new DNA into the patient’s cells. Cells, however, are designed to keep things out. That’s why they have wrappers, called cell membranes. Scientists needed vectors: gene delivery...
