New strategy to reverse the disease dyskeratosis congenita

New strategy to reverse the disease dyskeratosis congenita
A link between telomeres and a molecular signaling cascade called the Wnt pathway has been identified by researchers, which may point to a treatment option for dyskeratosis congenita patients. Dyskeratosis congenita, or DC, is a rare, inherited disease for which there are limited treatment options and no cure.

Scientists find potential treatment for ‘painful blindness’ form of dry eye

Scientists find potential treatment for 'painful blindness' form of dry eye
The researchers solved this problem by developing markers to label the cells of interest and then testing different enzymes and other reagents to draw them out of tissues. A new study in animal models, led by scientists at The Scripps Research Institute (TSRI), suggests that the eye’s lacrimal glands can be repaired by injecting a kind of regenerative “progenitor” cell. The findings...

Researchers find new functions of blood cell protein in transplant

Researchers find new functions of blood cell protein in transplant
Scientists have found exciting, new functions of the protein angiogenin that play a significant role in the regulation of blood cell formation, important in bone marrow transplantation and recovery from radiation-induced bone marrow failure. Since current bone marrow transplantations have significant limitations, these discoveries may lead to important therapeutic interventions to help improve the...

Unproven stem cell therapies for lung disease on the rise despite promise of new treatments

Unproven stem cell therapies for lung disease on the rise despite promise of new treatments
Stem cell medical tourism and unproven stem cell interventions are growing and concerning issues for patients afflicted with lung disease. According to researchers, there are an increasing number of clinics worldwide offering expensive stem cell-based therapies that are ineffective or have no proven benefit.

Hybrid treatment hunts down and kills leukemia cells

Hybrid treatment hunts down and kills leukemia cells
Researchers have developed a hybrid treatment that harnesses a monoclonal antibody to deliver antisense DNA to acute lymphoblastic leukemia (ALL) cells and that may lead to less toxic treatments for the disease.

Sub-set of stem cells found to minimize risks when used to treat damaged hearts

Sub-set of stem cells found to minimize risks when used to treat damaged hearts
Scientists use mathematical modeling to simulate human mesenchymal stem cell delivery to a damaged heart and found that using one sub-set of these stem cells minimizes the risks associated with this therapy. The study represents a development in novel strategies to repair and regenerate heart muscle and could improve stem cell treatments for heart attack patients.

ALS research suggests stem cells be ‘aged’ to speed progress toward finding treatments

ALS research suggests stem cells be 'aged' to speed progress toward finding treatments
Scientists are seeking to build an improved stem-cell model of amyotrophic lateral sclerosis (ALS) to accelerate progress toward a cure for the devastating neurological disorder. Their findings demonstrate that current models can be enhanced by the aging of motor neurons to show how ALS damages cells later in life.

Protein found to bolster growth of damaged muscle tissue

Protein found to bolster growth of damaged muscle tissue
Biologists have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could contribute to treatments for muscle degeneration caused by old age or muscular dystrophy.

Discovery of insulin-producing beta cell subtypes may impact diabetes treatment

Discovery of insulin-producing beta cell subtypes may impact diabetes treatment
Researchers have determined the existence of at least four separate subtypes of human insulin producing beta cells that may be important in the understanding and treatment of diabetes.

Surprising number of businesses selling unapproved stem cell ‘treatments’ in the US

Surprising number of businesses selling unapproved stem cell 'treatments' in the US
At least 351 companies across the United States are marketing unapproved stem cell procedures at 570 individual clinics. Such businesses advertise ‘stem cell’ interventions for orthopedic injuries, neurological disorders, cardiac diseases, immunological conditions, pulmonary disorders, injured spinal cords, and cosmetic indications. A stem cell researcher now presents an analysis of US...
