Sickle cells can get stuck in the blood vessels, causing severe and chronic pain , infections, and other complications. (medlineplus.gov)

The resultant hemoglobin molecules tend to clump together into long polymers, making the red blood cell (RBC) elongated (sickle-shaped), rigid and unable to deform appropriately when passing through small vessels, resulting in vascular occlusion. (radiopaedia.org)

This treatment takes a patient's stem cells and edits them to produce more fetal hemoglobin, an abundance of which has been observed to cause red blood cells to not "sickle. (wkbn.com)
