ITALY – Study: Tumor Stem Cells Key in Fighting Cancer

The key to eradicating tumors and preventing relapses and metastasis is buried within the tumor itself. The tumor cells themselves contain a sort of needle in the haystack. Just 1% of the total volume of the tumor is responsible for reproduction, and a targeted surgery or drugs could be sufficient enough to “deactivate” the tumor and avoid any possibility of a reoccurrence. This type of treatment could possibly change the therapeutic approach to malignant tumors according to an Italian study at the Superior Health Institute (ISS) by Professor Ruggero De Maria, the Director

Common Virus Kills Breast Cancer Stem Cells

Dalhousie Medical School cancer researcher Dr. Patrick Lee has proven that a common virus can infect and kill breast cancer stem cells. This breakthrough finding is published in the current issue of Molecular Therapy, the journal of the American Society of Gene Therapy.

It is only within the past few years that the scientific community has understood the full significance of cancer stem cells and the urgent need to find a means of eliminating them.

“Cancer stem cells are essentially mother cells,” explains Dr. Lee, Cameron Chair in Basic Cancer Research at Dalhousie Medical School. “They continuously produce new

German Study Discovers Stem Cell ‘Silent’ Reserves

Andreas Trumpp

Andreas Trumpp and his colleagues from the German Cancer Research Center have recently spoken about a “silent reserve” of stem cells, wondering what type of medical impact the discovery made in Heidelberg of “dormant stem cells” could have.

Usually, dormant bone marrow cells activate and multiply only in a crisis or emergency to react to serious cellular loss due to a virus or hemorrhage. When their work is done, they return to a dormant stage. This withdrawal phase keeps them protected from mutations, cellular toxins, and other dangerous substances, since the cells do not divide

ITALY – Pisa. Hematopoietic stem cell collection center opens

The Pisa University Hospital has become part of the international network of hematopoietic stem cell transplant facilities (meaning they produce various blood components). The hospital was recently accredited by the Italian registry of bone marrow donors, which is part of the international network.

Pisa has become an important center for bone marrow collection for all potential donors in northwestern Italy.
On 20 April 2009, the first donation was carried out for a patient at the Udine University Hospital, and a second donation is being organized for a patient being treated at the Montpellier Hospital (France).

The hospital in Pisa received the

POTENTIAL NEW “TWIST” IN BREAST CANCER DETECTION

December 4, 2009- Working with mice, scientists at Johns Hopkins publishing in the December issue of Neoplasia have shown that a protein made by a gene called “Twist” may be the proverbial red flag that can accurately distinguish stem cells that drive aggressive, metastatic breast cancer from other breast cancer cells.

Building on recent work suggesting that it is a relatively rare subgroup of stem cells in breast tumors that drives breast cancer, scientists have surmised that this subgroup of cells must have some very distinctive qualities and characteristics.
