Adult stem cells hold promise in the treatment of ischemic stroke and other neurological disorders, including Parkinson's disease, amyotrophic lateral sclerosis, traumatic brain injury and cerebral palsy. Aldagen's technology isolates specific populations of adult stem cells that express high levels of aldehyde dehydrogenase (ALDH-bright cells). Preclinical studies conducted by leading research institutions and academic centers have shown that ALDH-bright cells from bone marrow and cord blood may be able to repair neural tissue, which hold promise for the treatment of damaged tissue in the brain from ischemic stroke.
Martha O'Donnell, professor of physiology and membrane biology, and Jan Nolta, director of the new UC Davis Institute for Regenerative Cures -- a facility supported by the California Institute for Regenerative Medicine, will lead the ischemic stroke research effort at UC Davis.
"Aldagen's technologies for stem cell isolation offer an approach for developing therapies that may be successful in clinical practice," said Nolta, who recently participated in groundbreaking ceremonies for UC Davis' $100 million regenerative cures facility in Sacramento "The promise and potential of our stem cell work is greatly enhanced by this type of collaborative partnership with private industry."
"It is exciting to see the wide range of stem cell work now taking place at UC Davis," said Ed Field, president and chief operating officer at Aldagen. "They've been able to recruit a team of internationally recognized stem cell experts, which complements the focus we have at Aldagen. We look forward to working with Jan Nolta and Martha O'Donnell to further expand our portfolio in vascular biology and to explore the potential of our stem cell therapies for the treatment of neural disease."
According to the American Stroke Association, nearly 800,000 people a year suffer a new or recurrent stroke. It is the third leading cause of death and the leading cause of disability in adults. This year, Americans will pay about $65.5 billion for stroke-related medical costs and disability.
Current treatment for an ischemic stroke calls for the immediate use of a clot-busting drug, which must be administered within three hours of the event. Stem cells as therapeutics may represent a novel approach to the treatment of ischemic stroke because both blood vessels and neural tissue in the brain need to be restored. ALDH-bright cells have been shown to induce formation of new vessels in animal models. In mouse models, ALDH-bright cells have also restored functional nerves and ameliorated symptoms for inherited lethal human nervous system diseases.
Nolta says she looks forward to testing Aldagen's stem cell populations in the stroke models that O'Donnell's laboratory has established, and hopes that the collaborative research agreement with the company will lead to the types of clinical trials already in the planning process at UC Davis. With construction of its new research facilities in Sacramento, researchers hope to begin clinical research studies by the end of 2009 using adult stem cells to test the effectiveness of revascularization of blood vessels in the legs of patients with chronic vascular disease. Plans also call for clinical trials using regenerative medicine for treating Huntington's Disease, heart attacks and retinal occlusion.
"We're planning to have some of our key laboratories in the stem cell institute's new building up and running by late next year," said Nolta. "Those facilities will play a key role in enabling us to advance cellular therapies for treatments of numerous life-threatening diseases."
About UC Davis stem cell research
UC Davis has more than 125 scientists working on a variety of stem cell investigations in both Davis and Sacramento. The California Institute for Regenerative Medicine (CIRM) has awarded more than $34 million to researchers at UC Davis to develop stem cell cures. The programs are designed to expedite the translation and integration of scientific research into discoveries and treatments that benefit society. The university is currently constructing a 90,000 square foot stem cell research facility on its campus in Sacramento, where researchers will have access to state-of-the-art laboratories and cell manufacturing and testing rooms. Inside the institute will be a state-of-the-art Good Manufacturing Practice facility, which is a state of the art, cleanroom environment that allows researchers to process and isolate specific stem cells. That project, along with the Translational Human Embryonic Stem Cell Shared Research Facility in Davis, help complement the university's Clinical and Translational Science Center, which is supported by the National Institutes of Health (NIH). In 2005, the NIH awarded $6 million to fund a Center of Excellence in Translational Human Stem Cell Research on the Davis campus. One of only two such centers in the nation, it is focused on exploring stem and progenitor cell therapies for the treatment of childhood diseases.
