Table of Contents Introduction How the Study Worked Key Findings What We Still Don’t Know Why It Matters Disclaimer Acknowledgements Introduction Genetic blood disorders like sickle cell disease and β-thalassemia affect millions worldwide, often requiring lifelong treatments such as blood transfusions and medications. Recent breakthroughs in biotechnology, particularly CRISPR–Cas9 gene editing, offer the possibility of correcting these genetic defects at their source, potentially providing long-term cures rather than just managing symptoms. This article summarizes a 2019 study published in Nature Medicine , exploring how CRISPR can be used to edit human hematopoietic stem cells (HSCs) to correct mutations responsible for these blood disorders. How the Study Worked Researchers extracted hematopoietic stem cells from patients with sickle cell disease or β-thalassemia...
