Stem cell breakthroughs to look for
The Short List
Kuehl sees better -- she's back to hiking, other everyday activities, and enjoying beating out her spouse on seeing the tiny ships first. Treatments for eye diseases are considered among the most promising for stem cells, which have been under study for more than 3 decades. While proponents say all this groundwork is finally coming to fruition, others call progress slow and plodding. But, he says, one type of stem cell often researched, the induced pluripotent stem cell, was only discovered in These are adult stem cells reprogrammed to work like embryonic stem cells.
Researchers also use embryonic stem cells, derived from embryos and grown in a lab, and adult stem cells from tissues and organs. Keck provost and university professor at the University of Southern California. In comparison, Wells says, prescription drugs often take 15 years to progress from research stages to market. On its ''clinical dashboard" page, CIRM, California's stem cell agency, lists 56 clinical trials it has funded.

Of the 56, only six are in phase 3, the final before seeking approval. But one of those phase 3 studies has been terminated and another suspended. On clinicaltrials. Ask experts about stem cell successes, and many mention the "Bubble Boy" disease treatment, reported earlier in The treatment is for a rare genetic defect that robs infants of an immune system and can lead to severe infection.
Treatment is crucial to avoid death.
Researchers first obtain blood-forming stem cells from a patient's bone marrow, deliver a normal gene to the cell, then infuse the stem cells back into the patient. The genetically corrected system cells settle in and start producing new blood cells. Macular degeneration: The study that Anna Kuehl took part in was a phase study. Four patients received the implant.
All had stable or improved vision. Improving by three lines on an eye chart, as anyone with a vision problem knows, he says, "is huge. Kashani is hoping to begin another phase 2 study in to evaluate patients with less advanced macular degeneration. Kidney transplant: Patients who receive a kidney transplant must take immunosuppressive drugs to prevent organ rejection for life. The medications have risks, such as becoming toxic and increasing a patient's risk of infection, heart disease, cancer, and diabetes. Now, researchers are infusing stem cells and immune cells from the organ donor into the patient who received the donor kidney.
The hope is to stop the need for the immunosuppressive drugs. The research is now in phase 3, with an estimated enrollment of Researchers want to show that the approach is safe and effective, and see if it ends the need for the immunosuppressive drugs. The study is due to be completed in January Diabetes: Other researchers are working on using embryonic stem cell therapy to treat type 1 diabetes, which happens when the immune system destroys the beta cells in the pancreas that make insulin.
Recent Advancements in Stem Cell Treatments
Researchers have found a way to turn human embryonic stem cells into ones known as pancreatic progenitor cells. These can then mature into insulin-making beta cells. The research is in phases 1 and 2, to test the safety of putting a device containing the progenitor cells into 69 people with type 1 diabetes.

Many people talk about the semiconductor being the dominant discovery in the last 50 years. Now, many think biotech will be the major driver of advancements in the coming 50 years.
California promises to be an epicenter for that. We need to be advocating for policies worldwide that would accelerate the safe and effective use of stem cell medicine. Our professional society plays a key role in educating not just governmental entities, but the public, helping them understand how we plan to resolve human disease.
