Breakthrough: Human Hearts Can Grow New Cells
4/20/2009 11:50:00 AM
In the April 3 issue of the journal Science, a team from University of Toronto and University of Wisconsin-Madison announced their discovery that heart cells regenerate throughout a human lifetime, with a 1 percent annual turnover rate at age 25, falling to a 0.45 percent turnover rate at age 75. Therefore, the human heart must have it's own stem cells.

World's Second Human Trials of Embryonic Stem Cells May Make the Blind See Again
4/20/2009 11:00:00 AM
In what would be the second human trials of embryonic stem cells (the first for spinal cord injuries), a UK team is applying for regulatory approval from the Medicines and Healthcare products Regulatory Agency, the Human Tissue Authority, in order to replace damaged cells caused by age-related macular degeneration (AMD), the most common cause of blindness. Embryonic stem cells will be re...

Breakthrough?: British Scientists to Create Unlimited Blood Supply From Embryonic Stem Cells
3/23/2009 9:09:00 AM
Imagine ending the need for blood drives. UK teams at NHS Blood and Transplant, the Scottish National Blood Transfusion Service and the Wellcome Trust, the world's biggest medical research charity, may do just that. These scientists are working on becoming the world's first producers of unlimited amounts of artificial human blood from embryonic stem cells for blood transfusions.<...

Breakthrough: Induced Stem Cells Now Made Cancer Free
3/6/2009 9:30:00 AM
Since 2007, scientists have been able to reprogram adult stem cells, like skin, into (artificial) embryonic stem cells by using viruses or genes. However, these inserted viruses or genes had the potential to cause cancer or other problems. Dr. Rudolf Jaenisch' stem cell research team at MIT and the Whitehead Institute for Biomedical Research in Cambridge, Mass., recently found a way to ...

Policy: Are Embryonic Stem Cells Obsolete?
3/5/2009 9:50:00 AM
With the recent advances in reprogramming adult stem cells to mimic embryonic stem cells, and their increased survival rate in patients, has the need for embryonic stem cell research ended? Bernadine Healy, M.D., the former head of the National Institutes of Health, and the American Red Cross, states her case.

Breakthrough: Australian Scientists Regrow Mice Muscle Tissue from Adult Stem Cells
3/4/2009 10:05:00 AM
Australian scientists have become the first in the world to use adult stem cells (from a donor) to regrow damaged muscle tissue (in mice), offering hope to sufferers of muscular dystrophy. They overcame the problem of getting the donor cells to survive for more than an hour.

Breakthrough: UCLA Team Creates Nerve Cells From Skin - Bypassing Embryos
2/25/2009 10:27:00 AM
A team from the University of California Los Angeles led by William Lowry, created the first motor neurons from artificial embryonic stem cells, called induced pluripotent stem cells, or iPS cells, which were in turn created from ordinary skin cells. This has huge implications for the debate over the use of and need for embryonic stem cells. Their next step is to attach their neur...

Human Trials: Man Cured of Multiple Sclerosis Using Adult Stem Cells
2/23/2009 11:40:00 AM
A Northwestern University clinical trial using adult stem cells 'cures' Edwin McClure, a Virginia Commonwealth University advertising graduate student with multiple sclerosis. Stem cells were removed from his bone marrow and grown in a lab. His existing cells were destroyed by chemotherapy, then replaced by the new ones via injection. His symptoms have since disappeared.

Breakthrough: Can Stop Embryonic Stem Cells From Specializing
2/11/2009 3:20:00 PM
UK scientists have identified a chemical that will stop an embryonic stem cell from differentiating for several weeks so it is possible to can grow large numbers of them before they change into other cell types.

Human Trials: World's First Adult Stem Cells from Heart Tissue to Repair Heart
2/11/2009 3:00:00 PM
The world's first FDA-approved clinical trial using adult stem cells derived from heart tissue to treat heart disease will be conducted by a team of University of Louisville doctors at Jewish Hospital. Bypass patients will have some tissue re...

Further Advance in Artificial Stem Cells - Blood Platelets Created
2/9/2009 12:28:00 PM
1 comment
Kyoto University's Shinya Yamanaka and University of Tokyo's Naoya Takayama were the first in the world to generate induced pluripotent stem cells (iPS) cells (think artificial embryonic stem cells) using skin cells from mice in 2006, then in humans in November 2007. They have now proceeded to the next step by creating blood platelets using these cells. Editors Breakthrough: Longevity Gene Discovered 2/3/2009 5:20:00 PM
A German research group, with the Faculty of Medicine at the Christian-Albrechts-University in Kiel, discovered that the gene FOXO3A may have a positive effect on human life expectancy throughout the world.

Breakthrough: Australia Creates its First 'Artificial' Embryonic Stem Cells from Skin Cells
2/2/2009 9:30:00 AM
Australian scientists have produced their nation's first human induced pluripotent stem (iPS) cells - cells that act like embryonic stem cells but instead were made from adult skin cells. They now join the club of nations, Japan and the United States, that can skirt around the ethical issues of obtaining stem cells from embryos.

Breakthrough: World's First Extinct Animal Brought Back to Life - Through Cloning
2/1/2009 11:30:00 AM
For the first time ever, an extinct animal has been resurrected through cloning. A wild mountain goat, called a Pyrenean ibex, died out in the year 2000 in northern Spain. Skin samples were saved from the animal and kept frozen in liquid nitrogen.

Breakthrough: Origin of Blood Stem Cells Discovered
1/18/2009 11:50:00 AM
The timeline of development of blood (hematopoietic) stem cells (HSCs) from the embryo to bone marrow has been proven in mice by a research team led by Nancy Speck, PhD, Professor of Cell and Developmental Biology at the University of Pennsylvania School of Medicine. HSCs are found in the bone marrow of adults and generate all of the blood cell types in the body. During developmen...

Breakthrough: Scientists Can Now Tell The Difference Between a Normal Stem Cell and Cancer Stem Cell
1/9/2009 3:30:00 PM
Canadian scientists have announced for the first time how to tell the difference between normal stem cells and cancer stem cells in humans. In time, this will allow doctors to kill the cancerous cells, and to only grow good cells.
