Toronto researcher's discovery points to a new treatment avenue for acute myeloid leukemia
Dr. John Dick, Senior Scientist at the Ontario Cancer Institute, the research arm of Princess Margaret Hospital, co-led a multinational team that has developed the first leukemia therapy that targets a protein, CD123, on the surface of cancer stem cells that drive acute myeloid leukemia (AML), which is an aggressive disease with a poor outcome. view more (2009-07-07)
Stem cells decrease ischemic injury and restore brain function
This is the impressive result of a study carried out by a group of researchers coordinated by Dr. Maria Grazia De Simoni of the Mario Negri Institute in Milan, Italy in cooperation with the Istituto Neurologico Besta (Milan) and the University of Lausanne. view more (2007-04-18)
New tool illuminates connections between stem cells and cancer
Researchers have a new tool to understand how cancers grow -- and with it a new opportunity to identify novel cancer drugs. They've been able to break apart human prostate tissue, extract the stem cells in that tissue, and alter those cells genetically so that they spur cancer. view more (2010-02-22)
A twist of fate -- Reprogrammed fibroblasts resemble embryonic stem cells
Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline. view more (2007-06-07)
Clues to breast cancer hidden inside stem cells
Stem cells and how to boost them is hot on the research agenda. But stopping them could be critical too, as evidence implicating stem cells in cancer is mounting. view more (2006-04-25)
Stem cell breakthrough offers diabetes hope
Scientists have discovered a new technique for turning embryonic stem cells into insulin-producing pancreatic tissue in what could prove a significant breakthrough in the quest to find new treatments for diabetes. view more (2008-04-03)
Stem cell therapy for spinal injury
Researchers at Karolinska Institutet have shown how the transplantation of stem cells improves recovery from spinal injury. However, a painful condition can also develop, which can be prevented if the stem cells are supplemented with a certain gene that controls their maturing process. The results are important for planning of stem cell therapy... view more... (2005-02-13)
Stem cell therapy successfully treats heart attack in animals
Final results of a study conducted at Johns Hopkins show that stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs. view more (2005-07-26)
New source of multipotent adult stem cells discovered in human hair follicles
Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. view more (2006-07-13)
Cancer scientists create 'human' leukemia process to map how disease begins, progresses
Cancer researchers led by Dr. John Dick at Ontario Cancer Institute (OCI) have developed a method to convert normal human blood cells into "human" leukemia stem cells. view more (2007-04-27)
Researchers grow stem cells from human skin
Researchers at Wake Forest University School of Medicine have successfully isolated stem cells from human skin, expanded them in the laboratory and coaxed them into becoming fat, muscle and bone cells. The study, one of the first studies to show the ability of a single adult stem cell to become multiple tissue types, is reported today in Stem... view more... (2005-06-23)
Stem cells speed growth of healthy liver tissue
For the first time, researchers have used adult bone marrow stem cells to regenerate healthy human liver tissue, according to a study published in the April issue of the journal Radiology. view more (2007-03-27)
Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage and muscle. view more (2008-09-22)
Mass. General study finds potential ovarian cancer stem cells
Massachusetts General Hospital (MGH) researchers have identified potential ovarian cancer stem cells, which may be behind the difficulty of treating these tumors with standard chemotherapy. view more (2006-07-24)
Menstruation proves more than a curse
The cells which thicken the womb wall during a woman's menstrual cycle contain a newly discovered type of stem cell, and could be used in the treatment of damaged and/or old tissue. view more (2007-11-15)
Blood vessel cells are instructed to form tube-like structures
How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific journal Blood, might be an important step towards... view more... (2008-08-29)
Discovery makes brain tumor cells more responsive to radiation
Duke University Medical Center researchers have figured out how stem cells in the malignant brain cancer glioma may be better able to resist radiation therapy. view more (2009-12-03)
Drug has ability to cure type of leukemia
In people with chronic myeloid leukemia (CML), the drug Imatinib has been shown to drive cancer into remission, but the disease often returns when treatment is stopped. view more (2007-10-03)
World-first stem cell research could aid male infertility
Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring. view more (2006-07-11)
Protein key to control, growth of blood cells
New research sheds light on the biological events by which stem cells in the bone marrow develop into the broad variety of cells that circulate in the blood. The findings may help improve the success of bone marrow transplants and may lead to better treatments for life-threatening blood diseases. view more (2008-08-14)
