Master stem cell capable of producing new heart tissue

Researchers in the United States believe they have discovered a "master" embryonic cardiac stem cell.

Low-field magnetic separation of monodisperse Fe3O4 nanocrystals

Whether the goal is to separate different types of cells or molecules, methods that rely on the age-old principle of magnetism are a staple among researchers.

HRSA to allocate $14M to public umbilical cord blood banks

HHS' Health Resources and Services Administration plans to allocate $14 million to public umbilical cord blood banks nationwide in an effort to increase the supply of cord blood from 50,000 to 150,000 units, the AP/Washington Post reports.

The murine abdominal adipose stromal cell compartment supports the differentiation into endothelial, but not into hematopoietic progenitor cells

World Congress of Cardiology Report - Post-infarct regeneration of the damaged myocardium is critical for treatment of patients with acute coronary syndrome or myocardial infarction.

Regulatory T cells learn what to protect while in the thymus and that everything the cells learn may not be good

Regulatory T cells, which function like immune system police, learn early in life what to protect, and that may include viruses, bacteria and tumors, researchers have shown.

Researchers isolate rare cancer stem cells that cause leukemia

Researchers at Dana-Farber Cancer Institute and Children's Hospital Boston and their colleagues have isolated rare cancer stem cells that cause leukemia in a mouse model of the human disease.

Dopamine drug leads to new neurons and recovery of function in Parkinson's

In preliminary results, researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease (PD).

Dopamine drug may lead to new ways of treating Parkinson's and other neurodegenerative diseases

Researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease

University of Florida finding could lead to approaches to treat macular degeneration

University of Florida scientists conducting experiments with mice have found evidence that the body naturally replenishes small amounts of cells in the eye essential for healthy vision.

Type 1 diabetes results from selective destruction of pancreatic islet beta cells

IDDM, which used to be referred to as Type 1 diabetes, results from selective destruction of insulin-producing pancreatic islet beta cells by the body's immune system.

Signaling pathways required for expansion of insulin-producing beta cells

IDDM, which used to be referred to as Type 1 diabetes, results from selective destruction of insulin-producing pancreatic islet beta cells by the body's immune system.

SOX2 neural stem cell gene important in eye development

Scientists at the University of North Carolina at Chapel Hill have demonstrated that normal development of the eye requires the right amount of a neural stem cell gene be expressed at the right time and place.

New insight into the way an embryonic retina cell develops

The discovery provides a new vantage point for understanding how a healthy visual system develops. It also raises the possibility of re-directing the production of cell types as needed to stave off eye disease.

DARPA grant supports research toward realizing tissue regeneration

While U.S. soldiers fighting in Iraq and Afghanistan are surviving injuries that in previous conflicts likely would have been fatal, the number of wounded with major tissue loss has never before been so high.

Compensation by tumor suppressor genes during retinal development in mice and humans

Humans are more susceptible to developing the eye cancer retinoblastoma than mice because, unlike humans, mice can compensate for the loss of activity of a gene critical to normal retinal development, according to results of a study by investigators at St. Jude Children's Research Hospital.

Placental growth factor may help body repair heart attack damage

Heart attack patients produce higher levels of a natural substance in the body that plays a role in the growth of new blood vessels and this over-expression of placental growth factor (PlGF) may help reduce damage to the heart muscle

Single dose of stem cells produce robust behavioral recovery in animal models for stroke, cerebral palsy

A single dose of adult donor stem cells given to animals that have neurological damage similar to that experienced by adults with a stroke or newborns with cerebral palsy can significantly enhance recovery from these types of injuries, researchers say.
