Stem cell infusion and hyperbaric oxygen treatment improve islet function in diabetes

16.03.2009
A study to determine if patients with type 2 diabetes can benefit from a combination of autologous (patient self-donated) stem cell infusions (ASC) and hyperbaric (above the normal air pressure of ) oxygen treatment (HBO) before and after ASC has found "significant benefits" in terms of "improvements in glycemic control" along with "reduced insulin requirements."

The combination therapy could decrease type 2 diabetes morbidity and mortality, said the authors, who published their study results in the latest issue of Cell Transplantation (Vol. 17 No.12).

"Autologous stem cell therapies are an emerging set of therapies with promising results and low side effects profiles," said corresponding co-author Esteban Estrada, MD, of Stem Cell Argentina. "In addition, hyperbaric oxygen therapy, used primarily in the treatment of carbon monoxide poisoning, air embolism suffered by divers, and as an enhancement to wound healing, has been shown to increase stem cell mobilization and the release of endothelial progenitor cells via a nitric oxide-dependent mechanism."

The clinical trial evaluated the safety of ASC-HBO combination treatment in 25 patients with type 2 diabetes.

According to the researchers, it is well known that with type 2 diabetes, there is an ongoing inflammation of the pancreas. Their hypothesis suggested that mobilizing stem cells would cause the growth of blood vessels (angiogenesis) and release factors that would result in the local differentiation of progenitor cells with a resulting anti-inflammatory effect. Diabetes, they added, has been shown to impair progenitor cell mobilization, a problem that local stem cell infusion could remedy.

Once more, the effect of the hyperbaric oxygen therapy, they hypothesized, would be to increase stem cell mobilization in such a way as "to target more than one crucial reparative step" to counteract the chronic injury that attack the endothelial progenitor cells and the islet cells.

"Overall, our results show that a close follow-up with intensive diabetic management alone could not be the only cause of the positive, progressive and consistent outcomes we obtained in this trial over one year of follow-up," said Dr. Estrada.

"A decade ago, research had explored stem cell transplantation and hyperbaric oxygen therapy as stand alone treatments. This study highlights the potential benefits of using an unusual combination therapy to treat diabetes" said Dr. Cesar V Borlongan, Associate Editor of Cell Transplantation and Professor at the University of South Florida College of Medicine.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
