Correcting Sickle Cell Disease With Stem Cells

Using a patient’s own stem cells, researchers at Johns Hopkins have corrected the genetic alteration that causes sickle cell disease (SCD), a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene.

The research team cautions that the work, done only in the laboratory, is years away from clinical use in patients, but should provide tools for developing gene therapies for SCD and a variety of other blood disorders.

Bioheart Announces Cell Therapies Program in the Middle East for Congestive Heart Failure and Peripheral Arterial Disease Patients

(…) Bioheart’s MyoCell® is a regenerative cell therapy that uses myoblasts, or muscle stem cells, that are grown from a patient’s own muscle. MyoCell® has been tested successfully on patients in four clinical trials. The REGEN trial is designed to test the safety and effectiveness of a composition of muscle stem cells that have been gene-modified to induce a greater than usual release of the SDF-1 protein. The SDF-1 protein is a molecule in the human body that, after an injury, is naturally released by most tissues to attract stem cells. The stem cells assist with the healing process.
