Drs. Scott Kitchen, Zoran Galic, Jerry Zack of the UCLA Broad Stem Cell Research Center and AIDS Institute and their colleagues demonstrated for the first time that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells. The process could potentially be used against a range of chronic viral diseases.

The study, published Dec. 7 in the-peer reviewed online journal PLoS ONE, provides proof-of-principle, a demonstration of feasibility, that human stem cells can be engineered into the equivalent of a genetic vaccine.

“We have demonstrated in this proof-of-principle study that

USA – MS: Autologous Stem Cell Transplants, Visible Progress in 8 of 10 Patients

Transplanting stem cells from one’s own bone marrow (autologous stem cell transplants) improves the symptoms of muscular sclerosis (MS), and in some cases the neurological disease actually regressed. These are the encouraging results obtained from a small study performed on 21 remittent MS patients by a group from the Northwestern University School of Medicine in Chicago and published in Lancet Neurology. “All of the patients,” said the neurologists, “witnessed an improvement in their conditions three years after the stem cell transplants were performed. Of these, 81pct benefited from visible progress, measured in terms of

How to cure cancer using stem cells

Historic Hurd Hall on Johns Hopkins’ East Baltimore campus was filled to capacity on Jan. 13 with students, faculty and staff waiting to hear five scientists—all in the early part of their careers—describe their novel ideas on how to cure metastatic cancer.

The five were finalists, chosen from among 44 entrants, in a competition on creative thinking named for John Rangos Sr., chairman of the Rangos Family Foundation, who funded the awards. Each scientist had 10 minutes to present his or her idea and answer questions from a panel of faculty judges, who would select the winners based on the

Using the immune system to better stem cell transplant results

A novel therapy in the early stages of development at Virginia Commonwealth University Massey Cancer Center shows promise in providing lasting protection against the progression of multiple myeloma following a stem cell transplant by making the cancer cells easier targets for the immune system.

Outlined in the British Journal of Hematology, the Phase II clinical trial was led by Amir Toor, M.D., hematologist-oncologist in the Bone Marrow Transplant Program and research member of the Developmental Therapeutics program at VCU Massey Cancer Center. The multi-phased therapy first treats patients with a combination of the drugs azacitidine and lenalidomide. Azacitidine

ITALY – Stem Cells. New Method to Combat Immunodeficiencies in Children at San Raffaele in Milan

Maria Grazia Roncarolo

It was stunning to see them closed inside of those plastic bubbles, kept far from all external contact because their immune system does not react against any foreign antigens. Today scientists can say that ADA-SCID (adenosine deaminase deficiency), a serious combined immunodeficiency caused due to a lack of the adenosine deaminase enzyme, has been definitively defeated by gene therapy developed at San Raffaele of Milan.

The final study, which combined the conclusions of clinical studies, which began in 2000 on strategic therapies developed by the HSR-TIGET (San Raffaele Telethon Institute for Gene Therapy) group, led
