Spleen may be source of versatile stem cells

A year ago, Massachusetts General Hospital (MGH) researchers discovered that the spleen might be a source of adult stem cells that could regenerate the insulin-producing islets of thepancreas. In a follow-up to that unexpected finding, members of thesame team now report that these potential adult stem cells produce aprotein previously believed to be present only during the embryonicdevelopmen...

Source of molecular triggers in cutaneous T cell lymphoma identified

In a study published in the journal Blood, Yale scientists identify the molecular triggers that stimulate Cutaneous T Cell Lymphoma (CTCL) cells to clonally expand into large populations of malignant lymphocytes. CTCL is the most common adult malignancy of T lymphocytes, the white blood cells of the immune system. Finding CTCL triggering factors has been a major goal of Richard L. Edelson...

Finding Cures For Tropical Diseases: Is Open Source An Answer?

There's aparadigm in life science and drug development : only "lucrative""markets" get exploited by R&D companies. In many occasions I'veseen very promising drugs candidates or related research get cannedbecause no money was to be made with it, even if millions would havebeen saved worldwide. The usual strategy to avoid this fate is to finda drug candid...

Poplar trees redirect resources in response to simulated attack

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have applied some of the same techniques used in medical imaging to track the distribution of nutrients in poplar trees in response to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big he...

Placenta Is A Rich Source Of Blood Stem Cells

Researchers at Children's Hospital Boston and the Dana-Farber Cancer Institute report a surprising finding about embryonic development: the blood system begins to form not only in the embryo itself, but also in the placenta, the organ that nurtures the baby in utero. Meticulous experiments in mice revealed that the placenta harbors a large supply of hematopoietic (blood-forming) stem cells...

Indian Cherry: Richest Source of Vitiamin C

The West Indian Cherry or Acerola fruit (Malpighia Punicifolia L) is the richest source of Vitamin C known to man. Hundred grams of edible portion yields 1000 to 4000 mg of Vitamin C. The West Indian Cherry tree grows well in the tropical parts in India. Apart from Vitamin C, West Indian Cherry is rich in Vitamin A, potassium, calcium, phosphorus and carbohydrates. According to the s...

Stem cells - New and richer source found

A recent study by researchers at Kansas State University has found that Wharton's jelly, the cushioning material or matrix within the umbilical cord, is a rich and readily available source of primitive stem cells. These umbilical cord matrix cells, which show tell-tale characteristics of all stem cells, could provide the scientific and medical research community with a non-controversial and easil...

Platelets May Be The Source Of Gene Regulations

Researchers from University of Utah School of Medicine had reported that a key process in gene regulation could occur in human platelets. These are unique cells that are unusual because they don’t have a nucleus // (anucleate). Scientists long have thought the transformation of pre-mRNA into mature mRNA—called splicing—happens only in a cell’s nucleus. But using stem cells from human...
