Daley and Colleagues Create 20 Disease-specific Stem Cell Lines

11.08.2008
Researchers from the Harvard Stem Cell Institute and Stem Cell Program at Children’s Hospital Boston have produced a robust new collection of disease-specific stem cell lines, all of which were developed using the new induced pluripotent stem cell (iPS) technique.

Harvard Stem Cell Institute researcher George Q. Daley, MD, PhD, also associate director of the Stem Cell Program at Children’s Hospital Boston, and HSCI colleagues Konrad Hochedlinger and Chad Cowan have produced a robust new collection of disease-specific stem cell lines, all of which were developed using the new induced pluripotent stem cell (iPS) technique. The paper is being published in the August 6 on-line edition of the journal Cell.

The new iPS lines, developed from the cells of patients ranging in age from one month to 57-years-old and suffering from a range of conditions from Down Syndrome to Parkinson’s disease, will be deposited in a new HSCI “core” facility being established at Massachusetts General Hospital (MGH), HSCI co-director Doug Melton announced yesterday. The operations of the iPS Core will be overseen by a faculty committee, which Daley will chair.

The cell lines the researchers produced carry the genes or genetic components for 10 different diseases, including Parkinson’s Disease, Type I diabetes, Huntington’s Disease, Down Syndrome, a form of combined immunodeficiency (“Bubble Boy’s Disease”), Lesch-Nyhan syndrome, Gaucher’s Disease, and two forms of Muscular Dystrophy, among others.

“We wanted to produce a large number of disease models for ourselves, our collaborators, and the stem cell research community to accelerate research,” Daley said. “The original embryonic stem cell lines are generic, and allow you to ask only basic questions. But these new lines are valuable tools for attacking the root causes of disease. Our work is just the beginning for studying thousands of diseases in a petri dish,” he said.

Melton said that the HSCI iPS Core will serve as a repository for iPS cells produced by HSCI scientists. “The Core will also function as a technical laboratory to produce these disease- specific lines for use by scientists around the world,” Melton said. He went on to say that “the suite of iPS cell lines reported by the Daley group marks an important achievement and a very significant advance for patients suffering from degenerative diseases.

These disease-specific iPS cells are invaluable tools that will allow researchers to watch the development diseases in petri dishes, outside of the patients. And we have good reason to believe that this will make it possible to find new treatments, and eventually drugs, to slow or even stop the course of a number of diseases. In years ahead,” Melton said, “this report will be seen as opening the door to a new approach to develop therapies."

"One of our goals in creating the NIH Director's Pioneer Award programs was to enable exceptionally creative scientists to move quickly in promising new directions, thereby speeding the intellectual and technical breakthroughs needed to address major challenges in biomedical or behavioral research," said National Institutes of Health Director Elias A. Zerhouni, M.D. "This is certainly the case for Drs. Daley and Hochedlinger, who deployed their Director's award resources to advance our ability to use induced pluripotent stem cells for disease-specific studies and drug development."

Daley and his colleagues, led by first-author and Children’s researcher In Hyun Park, PhD, intentionally produced some stem cell lines for highly heritable, single-gene diseases, such as Gaucher’s; complex genetic syndromes, such as Down; and then complex diseases, such as Parkinson’s, that involve genetic, cellular, and perhaps environmental components.

“The cell lines available from the iPS Core will allow stem cell researchers around the world to explore possible gene therapies for some conditions, and will aid in the development of drugs for others,” Daley said.

While Daley, President of the International Society for Stem Cell Research, is enthusiastic about the promise of reprogramming studies, he is far from ready to abandon experiments with embryonic stem cells. Daley believes that reprogramming and ESC research must advance in tandem to bring cell therapy to the clinic as quickly as possible.

The study was supported by grants from the National Institutes of Health (NIH), an NIH Director's Pioneer Award of the NIH Roadmap for Medical Research, an NIH Innovator’s Award, the Burroughs Wellcome Fund, the Leukemia and Lymhoma Society, the Harvard Stem Cell Institute, Children’s Hospital Boston Stem Cell Program, the Stowers Medical Institute, and the Howard Hughes Medical Institute.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
