Sickle-Cell Gene Therapy involves editing patient stem cells using CRISPR technology to restore the production of fetal hemoglobin, which prevents red blood cells from becoming crescent-shaped (sickled) and clogging small blood vessels. This therapy aims to provide a curative treatment for sickle-cell disease.
Sickle-Cell Gene Therapy addresses the genetic defect causing sickle-cell disease by modifying stem cells to express more fetal hemoglobin, thus preventing the characteristic sickling of red blood cells and alleviating symptoms associated with the condition.
Patient stem cells are harvested, edited using CRISPR to increase the expression of genes responsible for producing fetal hemoglobin, which is less prone to sickling under low-oxygen conditions. The modified cells are then re-infused into the patient's body, where they can produce healthy red blood cells.
The manufacturing process involves cell harvesting, CRISPR gene editing in a controlled laboratory setting, followed by quality control checks before re-infusion into patients. This requires specialized facilities capable of handling genetically modified cells under strict regulatory guidelines.
Cells are first harvested from the patient and sent to a facility where they undergo CRISPR-mediated gene editing. The edited cells are then cultured and expanded before being re-infused back into the patient. The entire process is highly regulated and requires precise control over cell handling and environment.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and cryogenic storage requirements.
