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.

Horse Stem Cell Technique to be Tested on Humans
4/16/2009 9:00:00 AM
It's rare for veterinary medicine to lead human medicine, but race horses are a different breed. A stem cell technique that has been used to quickly repair the tendons of race horses will be tried in humans for the first time. British biotech firm MedCell Bioscience Ltd said on Wednesday it would start clinical tests within 12 months to extract Mesenchymal adult stem cells from a patien...

SHOCK: Obama Signs Bill Banning Federal Funding of Embryonic Stem Cells
3/13/2009 1:20:00 PM
President Obama signed H.R. 1105, the “Omnibus Appropriations Act, 2009 (aka omnibus appropriations bill) on Wednesday which included a hidden provision that explicitly bans federal funding of any "research in which a human embryo or embryos are destroyed, discarded, or knowingly subjected to risk of injury or death." This bill is counter to the claims of Obama made just Monday where "sc...

Video: Facts - What are Cancer Stem Cells?
3/8/2009 9:20:00 PM
Video about cancer stem cells by Dr. Mike Magee of Health Politics. Stem cells have these properties, they can: self-renew, multiply, and proliferate extensively. We normally think about stem cells as being good and having healing properties. But if those properties are subverted by the body, they may become "evil" stem cells and may cause cancer. (There is some dispute at this...

FLASH: Policy: Obama to Sign Embryonic Stem Cell Executive Order Monday
3/6/2009 4:06:00 PM
President Obama will sign an executive order Monday authorizing Federal funds to be used in embryonic stem cell research. This was widely expected. However, it is ironic this funding will be available just as embryonic stem cells may not be needed with the recent advances in 'artificial' embryonic stem cells (aka iPS or induced pluripotent cells).

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 ...

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...

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.

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 Video: What are Induced Pluripotent Stem Cells? June 25 2008 2/9/2009 6:00:00 AM
Induced Pluripotent Stem Cells were developed in 2007 by Shinya Yamanaka of Kyoto University. Dr. Yamanaka and his team derived the cells by adding proteins that reprogram adults cells, reverting them to their embryonic state. "These new cells are expected to live for a very long time while retaining the ability to form all of the different tissues found in a human body. iPSC cells do no...

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.

Human Trials: Adult Stem Cell Therapy Stabilizes Multiple Sclerosis Patients
2/1/2009 1:00:00 PM
Northwestern University researchers used stem cells from a patient's own body (adult stem cells) in 21 patients, 11 women and 10 men, with relapsing-remitting MS who had not responded to treatment. After three years, 17 patients improved. This is very hopeful since, most people with MS , after the 10 year mark, usually develop a secondary-progressive form of the disease, and experience ...
