Diabetic blindness: UVA IDs best source of stem cells to block vision loss

June 25, 2015 by · Leave a Comment 

University of Virginia School of Medicine researchers have taken a significant step forward in their efforts to use stem cells to block vision loss caused by diabetic retinopathy, a condition that affects millions of people with diabetes. The researchers have evaluated the best potential sources for adult stem cells to be used for that purpose, determining that cells taken from donors who do not suffer diabetes likely will be more effective than cells taken from patients’ own bodies.

Scientists regenerate bone tissue using only proteins secreted by stem cells

May 13, 2015 by · Leave a Comment 

Scientists have discovered a way to regrow bone tissue using the protein signals produced by stem cells. This technology could help treat victims who have experienced major trauma to a limb, like soldiers wounded in combat or casualties of a natural disaster. The new method improves on older therapies by providing a sustainable source for fresh tissue and reducing the risk of tumor formation that can arise with stem cell transplants.

Weakness of leukemic stem cells discovered

August 5, 2014 by · Leave a Comment 

Despite improved therapy, only one out of every two adult patients survive acute myeloid leukaemia (AML). The mean survival time for this disease, which predominantly occurs in the elderly, is less than a year for patients over 65 years. It is assumed that leukaemic stem cells, which cannot be completely eliminated during treatment, are the origin of relapse. However, as has been discovered by a team of Frankfurt-based researchers, these cells do have a weakness: In the current edition of the high impact journal “Cancer Research“, they report that the enzyme 5-lipoxygenase (5-LO) plays a significant role in the survival of leukaemic AML stem cells.

Stem cell-stimulating therapy saves heart attack patients

June 9, 2014 by · Leave a Comment 

Researchers at the Society of Nuclear Medicine and Molecular Imaging’s 2014 Annual Meeting revealed how a protein encourages the production of stem cells that regenerate damaged tissues of the heart following an acute attack (myocardial infarction). They further assert that it has a better chance of working if provided early in treatment. This was confirmed by molecular imaging, which captured patients’ improved heart health after therapy.

Study urges caution in stem cell clinical trials for heart attack patients

May 7, 2014 by · Leave a Comment 

A new study in Nature challenges research data that form the scientific basis of clinical trials in which heart attack patients are injected with stem cells to try and regenerate damaged heart tissue.

New human trial shows stem cells are effective for failing hearts

March 31, 2014 by · Leave a Comment 

Patients with severe ischemic heart disease and heart failure can benefit from a new treatment in which stem cells found in bone marrow are injected directly into the heart muscle, according to research presented at the American College of Cardiology’s 63rd Annual Scientific Session.

New method yields potent, renewable human stem cells with promising therapeutic properties

March 26, 2014 by · Leave a Comment 

The curative and therapeutic potential of mesenchymal stem cells (MSCs) offers much promise, as these multipotent cells are currently being tested in more than 300 clinical trials in a range of diseases. A new, easier, and more reliable way to make large quantities of highly potent MSCs could accelerate progress toward their use in regenerative medicine, as described in an article in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Stem Cells and Development website.

Critical factor (BRG1) identified for maintaining stem cell pluripotency

February 9, 2014 by · Leave a Comment 

he ability to reprogram adult cells so they return to an undifferentiated, pluripotent state—much like an embryonic stem cell—is enabling the development of promising new cell therapies. Accelerating progress in this field will depend on identifying factors that promote pluripotency, such as the Brg1 protein described in a new study published in BioResearch Open Access, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the BioResearch Open Access website.
