“Bridges <strong>of</strong> Hope” HDSA Michigan Chapter -11-<br />

are expected to restore the health <strong>of</strong> brain cells damaged by the mutant htt protein. This therapy has been shown to be<br />

effective in animal models <strong>of</strong> HD.<br />

The planned UC Davis trial for treating HD will target earlier phases <strong>of</strong> the disease, when patients are younger and before<br />

the illness's full impact takes its toll. Vicki Wheelock said that mesenchymal stem cells represent remarkably effective<br />

delivery vehicles because they move well through tissue and can produce high levels <strong>of</strong> growth factor for uptake by the<br />

damaged neurons. In preparation for its phase I clinical trial with HD patients, the <strong>Huntington's</strong> disease team is carefully<br />

testing its proposed cellular infusion therapy for safety and effectiveness.<br />

"The delivery <strong>of</strong> brain-derived neurotrophic factors via mesenchymal stem cells significantly reduces behavioral deficits<br />

in HD mice back to nearly normal levels," said Nolta, who has been working with Wheelock for the past several years in<br />

conducting the research for their successful grant proposal to CIRM. "We are doing further work to ensure that the proposed<br />

therapy will be safe and effective as we prepare for a clinical trial."<br />

For patients and their families, who have been tireless advocates for stem cell research, a multimillion dollar grant and<br />

the promise <strong>of</strong> a phase I clinical trial are breakthrough accomplishments in the fight to overcome <strong>Huntington's</strong> disease.<br />

"It's hard to put into words what this stem cell funding truly means for families like mine," said Judy Roberson, who lost<br />

both her 51-year-old husband and brother-in-law to the disease, and then went on to provide the impetus for establishing<br />

a multidisciplinary HD clinic at UC Davis. "The determination and dedication <strong>of</strong> Dr. Wheelock and Dr. Nolta, combined<br />

with CIRM's support, gives us the edge we need to overcome this terrible disease."<br />

Roberson and other patient advocates helped provide funding support to UC Davis at a crucial point in the university's<br />

stem cell research for HD. Also, a pilot grant from the university's Clinical and Translational Science Center, along with<br />

donations from two non-pr<strong>of</strong>it organizations - Team KJ and the Deshalamar Foundation - enabled Wheelock and Nolta to<br />

conduct the preliminary biosafety studies that were needed before the state stem cell agency would consider their <strong>Disease</strong><br />

Team grant proposal. Generous private philanthropy from the Roberson and Charles Pue families provided early<br />

support to the HD clinic at UC Davis, which is now a hub for clinical care and research trials and has followed over 300<br />

patients with the disease.<br />

To develop the proposed therapy to be used in the clinical trial, basic scientists and clinicians who comprise the <strong>Huntington's</strong><br />

disease team have met weekly for the past several years. Nolta noted that the team taps into expertise from<br />

throughout UC Davis, including the university's health system leadership, led by Claire Pomeroy, vice chancellor for Human<br />

Health Sciences and dean <strong>of</strong> the School <strong>of</strong> Medicine, and Fred Meyers, the school's executive associate dean.<br />

Wheelock credited her team's membership in the Huntington Study Group for developing expertise in conducting human<br />

HD research studies.<br />

"We are also consulting with national and international <strong>Huntington's</strong> disease experts," said Nolta. "But most importantly,<br />

the <strong>Huntington's</strong> disease community and patient advocates, who already have helped us make great strides through<br />

their philanthropy and participation in observational clinical trials, will continue to provide incredible inspiration for all <strong>of</strong><br />

us who are working to treat this heartbreaking disease."<br />

UC Davis is playing a leading role in regenerative medicine, with nearly 150 scientists working on a variety <strong>of</strong> stem cellrelated<br />

research projects at campus locations in both Davis and Sacramento. The UC Davis Institute for Regenerative<br />

Cures, a facility supported by the California Institute for Regenerative Medicine (CIRM), opened in 2010 on the Sacramento<br />

campus. This $62 million facility is the university's hub for stem cell science. It includes Northern California's largest<br />

academic Good Manufacturing Practice laboratory, with state-<strong>of</strong>-the-art equipment and manufacturing rooms for cellular<br />

and gene therapies. UC Davis also has a Translational Human Embryonic Stem Cell Shared Research Facility in<br />

Davis and a collaborative partnership with the Institute for Pediatric Regenerative Medicine at Shriners Hospital for Children<br />

Northern California. All <strong>of</strong> the programs and facilities complement the university's Clinical and Translational Science<br />

Center, and focus on turning stem cells into cures.<br />

Dr. Gary Dunbar’s Lab at Central Michigan University conducted earlier Stem Cell research as a basis for this grant.
