Stem Cells without Side Effects

September 26, 2008

Researchers at Harvard University, the Harvard Stem Cell Institute, and the MGH Center for Regenerative Medicine have found a way to create healthy stem cells from adult cells–no embryo required–using an adenovirus.

The adenovirus can make the transfer in mouse cells without permanently integrating itself. The resulting induced pluripotent stem (iPS) cells can divide indefinitely but show no trace of the virus–just a temporary infection that disappears within a… read more

Stem Cells without the Embryos

November 21, 2007

Kyoto University and University of Wisconsin scientists appear to have independently achieved one of regenerative medicine’s holy grails: reprogramming human adult cells to behave like embryonic stem cells, without the use of an embryo or a human egg.

The method could provide a way to make patient-specific stem cells, a feat not yet achieved in humans. Such cells could eventually be used for studying complex genetic diseases, or for… read more

Stem Cells: Promise, in Search of Results

August 24, 2004

At three Boston laboratories, the world of stem cell research can be captured in all its complexity, promise and diversity.

Stem-Cell Breakthrough

May 7, 2004

Scientists have found a way to convert stem cells in human fat to human bone cells when transplanted into a mouse.

This is an important step toward using stem cells for repair of broken bones, using stem cells donated by people who have gotten liposuction.

Stem-Cell Method May Cheat Death

December 23, 2004

A reproductive research team could have an answer to the ethical and scientific conundrums presented by the pursuit of stem-cell treatments: remove one cell from a very early embryo that has developed to about eight cells (called a morula), and derive stem cells from that single cell.

The embryo would still have the potential to develop into a human if implanted into a womb.

Stem-Cell Repair Kit for Stroke

March 9, 2009
(Bible E et al.)

A novel matrix of neural stem cells and biodegradable polymer PLGA developed at the Institute of Psychiatry at King’s College London can quickly repair brain damage from stroke in rats, growing new nerve tissue to fill stroke-induced cavities in just seven days.

Stem-cell reprogramming method not to blame for mutations: Scripps scientists

October 7, 2011

Scientists at the Scripps Research Institute have discovered that a reprogramming method is not to blame for dangerous mutations found within Induced Pluripotent Stem Cells (iPSC) — adult stem cells that have been genetically coaxed into behaving like embryonic stem cells. The discovery may help narrow down the exact cause of the mutations, long a roadblock to iPSC’s widespread use.

There have been a… read more

Stem-cell ‘secret of youth’ found

December 26, 2003

Researchers may have found a way to keep Human embryonic stem (ES) cells (which can generate almost all of the body’s different cell types) young.

The discovery solves two problems in this process: it controls the cells’ transformations into other types and eliminates the need for mouse cells, which could contaminate ES cells with mouse proteins.

Stem-cell therapy takes off in Texas

March 1, 2012

With Texas pouring millions of dollars into developing adult stem-cell treatments, doctors there are already injecting paying customers with unproven preparations, supplied by Celltex Therapeutics, which “multiplies and banks” stem cells derived from people’s abdominal fat and houses the largest stem-cell bank in the United States.

Texas governor Rick Perry, for instance, has had stem-cell injections to treat a back complaint1, and has supported legislation to help create banks… read more

Stem-Cell-Coated Contact Lenses Are Curing the Blind

June 4, 2009

By infusing contact lenses with a patient’s own stem cells from their good eye, test subjects reported a seemingly miraculous restoration of sight, say University of New South Wales researchers.

Stems cells as drug delivery carriers to the brain

December 15, 2005

Engineered human brain progenitor cells, transplanted into the brains of rats and monkeys, can effectively integrate into the brain and deliver medicine where it is needed, bypassing the blood-brain barrier, University of Wisconsin-Madison researchers have found.

The Wisconsin team obtained and grew large numbers of progenitor cells from human fetal brain tissue. They then engineered the cells to produce a growth factor known as glial cell line-derived neurotrophic factor… read more

Step forward for nanotechnology: Controlled movement of molecules

October 1, 2009

Scientists in the United Kingdom have found a way to get molecules to move quickly in a desired direction without help from outside forces, raising the possibility of coaxing cells to move and grow in specific directions to treat diseases.

The scientists used a special surface with hydrophobic (water repelling) and hydrophilic (water-attracting) sections. The region between the two sections produced an “energy gradient” that can move nanoscale objects… read more

Step Toward Universal Computing

September 13, 2004

Transitive Corp. of Los Gatos, California claims to have cracked one of most elusive goals of the software industry: a near-universal emulator (called QuickTransit) that allows software developed for one platform to run on any other, with almost no performance hit.

Step-by-Step Prompts Put the Blind on Track

October 18, 2002

A voice-controlled interactive personal navigation system could someday guide blind people. It communicates wirelessly with databases of detailed geographic information that can quickly be updated to reflect changing conditions.

Developed by University of Florida students, the Drishti (vision in Sanskrit) system can be configured to work in cities, in airports and on other campuses. It uses a wearable computer running I.B.M.’s ViaVoice software, connected to a GPS receiver and… read more

Stephen Colbert’s DNA to back up the human race

September 9, 2008

Comedy Central announced Monday that the host of The Colbert Report will have his DNA digitized and sent to the International Space Station (ISS) as part of the “Immortality Drive,” a time capsule that will include human DNA and records of humanity’s greatest accomplishments, along with personal messages collected specifically for the project.

We’re not making these up. -Ed.
