Stem cells join muscle, spinal cord cells in ‘human-on-a-chip’ simulation

November 24, 2011

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body.

.The National Institutes of Health (NIH), the Defense Advanced Research Projects Agency (DARPA), and the Federal Drug Administration (FDA) have recently launched an ambitious… read more

Stem Cells Made From ‘Dead’ Human Embryo

September 26, 2006

Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.

Stem cells made to mimic disease

April 8, 2008

Harvard Medical School and Nottingham scientists have taken skin cells from patients with eight different diseases and turned them into stem cells, moving one step closer to using stem cells from patients themselves to treat disease.

Stem Cells May Be Key to Cancer

February 21, 2006

At the heart of every tumor, some researchers believe, lie a handful of aberrant stem cells that maintain the malignant tissue.

The idea, if right, could explain why tumors often regenerate even after being almost destroyed by anticancer drugs. It also points to a different strategy for developing anticancer drugs, suggesting they should be selected for lethality to cancer stem cells and not, as at present, for their ability… read more

Stem cells may mend a broken heart

July 30, 2007

Stem cells may help repair damaged tissue after a heart attack, according to Harvard Medical School researchers.

Stem cells may protect brain, nervous system -study

July 15, 2005

Stem cells may protect the brain and nervous system against damage from tumors and conditions such as multiple sclerosis, researchers at Milan’s San Raffaele Scientific Institute found.

Experiments with mice with a disease similar to multiple sclerosis showed that stem cells injected into the blood stream migrated to inflamed areas in the brain and spinal cord, killing inflammatory cells.

Stem Cells Might Make Biological Pacemaker

December 21, 2004

Johns Hopkins researchers have found evidence that genetically engineered heart cells derived from human embryonic stem (ES) cells might one day be a biological alternative to the electronic pacemakers used by hundreds of thousands of people worldwide.

Human ES cells were grown in the lab and encouraged to become heart cells. The researchers then selected clusters of the cells that beat on their own accord, indicating the presence of… read more

Stem cells migrate from bone to brain

January 21, 2003

Autopsies on four dead women show for the first time that human stem cells in bone marrow can develop into brain cells. The discovery suggests new approaches for repairing damaged or diseased brains.

Stem cells rebuild bladder control

December 1, 2004

University Hospital, Innsbruck researchers used patients’ own stem cells to rebuild feeble bladder-control muscles.

The researchers removed a cube of muscle tissue from the women’s biceps. Stem cells from the tissue were extracted and then grown in culture for six weeks, producing about 50 million myoblasts – the precursors of muscle fibers. The myoblasts were then injected into the urethra wall and bladder sphincter, using real-time ultrasound to make… read more

Stem Cells Repair Blood Vessels

May 7, 2007

Scientists have developed a way to coax embryonic stem cells into a more adult form of stem cell that has the potential to form blood vessels. The new type of cells helped repair tissue in animals that had had heart attacks or eye damage due to diabetes.

Stem Cells Reshape Breasts After Cancer

December 19, 2007

Kyushu Central Hospital researchers have used fat-derived stem cells to help reshape the breasts of women who have undergone a lumpectomy to remove a breast tumor.

While the research is still early, it is thought that the stem cells develop into the cells needed to form new blood vessels.

Stem Cells Restore Cognitive Abilities Impaired By Brain Tumor Treatment

November 10, 2009

UC Irvine study research with rats found that transplanted human embryonic stem cells restored learning and memory to normal levels four months after radiotherapy.

Stem cells show power to predict disease, drug toxicity

December 7, 2007

UW-Madison researchers have found that human embryonic stem cells could be used for drug dicovery and screening, and could also generate chemical biomarkers that can be used to predict the onset of disease.

Stem Cells Used to Create Fertile Sperm in Mice

January 13, 2004

Scientists have coaxed stem cells from mice to change into immature sperm that can fertilize eggs to develop into embryos, an achievement that could pave the way for new ways of treating male infertility. The embryonic germ cells may also help scientists understand how erasure occurs and how stem cells are programmed to specialize and create different tissue and body parts.

Stem cells used to create retinal tissue

April 7, 2011

Retinal Tissue

Researchers at the RIKIN Four-dimensional Tissue Analysis Unit and colleagues in the Laboratory for Neurogenesis and Organogenesis and Kyoto and Osaka Universities have demonstrated how mouse embryonic stem cells (ESCs) are able to differentiate and assemble into an optic cup.

The study used a three-dimensional tissue culture system to demonstrate the self-organizing capacity of pluripotent stem cells┬áto give rise to a tissue exhibiting the stratified… read more
