Study Shows Conclusive Evidence on Role of Circulating Mesenchymal Stem Cells in Organ Injury

Mesenchymal stem cells (MSCs) are present in virtually every type of human tissue and after injury, it may help in organ regeneration.

But the theory that MSCs are released from the bone marrow into the blood stream following organ damage, and migrate to the site of injury, has long been debated. M.J. Hoogduijn and colleagues provide conclusive evidence to resolve the controversy over the mobilization and migration of MSCs in humans in a new study published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Stem Cells and Development website.

In "No Evidence for Circulating Mesenchymal Stem Cells in Patients with Organ Injury," Hoogduijn and coauthors from Erasmus University Medical Center (Rotterdam, The Netherlands), describe the results of studies to detect MSCs in the blood of healthy individuals, of patients with end-stage renal disease, of patients with end-stage liver disease, and of heart transplant patients with organ rejection. Whereas they did not find MSCs in the circulation of these individuals, they did report the presence of MSCs in the blood of a patient suffering from severe trauma with multiple fractures. In the trauma patient, the circulating MSCs likely derived from disruption of the bone marrow caused by the fractures.

"We can add the simple but elegant work of Martin Hoogduijn to the pantheon of studies in stem cell research that skewer a long treasured tenet of faith and consign it to mythology," says Editor-in-Chief Graham C. Parker, PhD, The Carman and Ann Adams Department of Pediatrics, Wayne State University School of Medicine, Detroit, MI.
