Stem cells are generating so much excitement in research and clinical circles because they have the capacity to become many other types of cells. They also release a number of important molecules such as hormones, cytokines, and genetic material that can potentially be helpful for patients. Researchers have found that not only does hyperbaric oxygen therapy (HBOT) help in the circulation of stem cells but it also will help to mobilize stem cells from the bone marrow to the bloodstream further preparing the patient for stem cell therapy.
Bone marrow is a rich source of stem cells, but getting them usually requires an invasive procedure, i.e., placing a large bore needle into the middle of bone(s). Researchers have discovered, however, that hyperbaric oxygen treatment causes stem cells from the bone marrow to move into the bloodstream by specifically stimulating the body’s nitric oxide synthesis. Thus, instead of using a needle to extract stem cells from the bone marrow, patients can potentially increase their own bone marrow stem cells by undergoing hyperbaric oxygen treatment.
Stephen Thom, MD, Ph.D. and co-researchers at the University of Pennsylvania showed that a single hyperbaric oxygen treatment could double the number of bone marrow stem cells in the blood. This means that the hyperbaric oxygen was “mobilizing” the stem cells to move from the bone marrow into the bloodstream to allow them to move into areas of the body that benefit from them. Moreover, when study subjects underwent 20 treatments of hyperbaric oxygen therapy over a few weeks, the number of bone marrow stem cells in the blood increased significantly by eightfold. This astonishing finding has been confirmed in subsequent experiments.
The most important conclusion from this research is that hyperbaric oxygen therapy treatments can unlock the potential of a person’s own bone marrow stem cells without an invasive procedure. While many scientists assumed that the benefits of hyperbaric oxygen therapy were due to the high concentrations of oxygen infusing the blood, tissues, and cells, they now have research to support that these benefits may also be due to stem cell mobilization.
