CRi's Oosight imaging system used for developing a gene transfer technique to prevent inherited diseases

U.S. researchers using CRi's Oosight(TM) imaging system have developed a gene transfer technique that has potential to prevent inherited diseases passed on from mothers to their children through mutated DNA in cell mitochondria.

Scientists cultivate multiple types of retina cells from human stem cells

A team of scientists from the University of Wisconsin-Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells — suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.

Sigma-Aldrich scientists to leverage proprietary gene editing technology to develop genetically-engineered rodent research models

Sigma-Aldrich(R) (Nasdaq: SIAL) announced today that scientists at its new Sigma Advanced Genetic Engineering (SAGE(TM)) Labs in St. Louis will leverage its exclusive CompoZr(TM) Zinc Finger Nuclease (ZFN) gene editing technology (www.compozrzfn.com) to define, develop and offer a new generation of genetically-engineered rodent research models. Such models are commonly used to study disease states in humans and play a key role in the drug discovery process.

Discovery of key factor that stimulates brain cancer cells to spread

Researchers funded by the National Institutes of Health have found that the activity of a protein in brain cells helps stimulate the spread of an aggressive brain cancer called glioblastoma multiforme (GBM). In a move toward therapy, the researchers showed that a small designer protein can block this activity and reduce the spreading of GBM cells grown in the laboratory.

$3.2M grant to explore how chemicals affect human health

Most people would agree that arsenic, lead, mercury, benzene and carbon monoxide pose dangers to humans. Not many, though, realize that the average person is exposed to about 10,000 different chemicals per day.

Only two stem cell lines account for most human embryonic stem cell research

For the past eight years, scientists who wanted to use federal funds for research on human embryonic stem cells had to restrict their studies to 21 cell lines approved by the National Institutes of Health. But an analysis by a researcher at the Stanford University School of Medicine suggests that only two of those lines have been used routinely.

Senators Harkin, Kennedy and Specter honored as champions of health research

The Foundation for the National Institutes of Health, Research!America and the Albert and Mary Lasker Foundation recognized these three senators for their continued support of research for health, their leadership and shared commitment to making it a high national priority, on Tuesday evening August 4th at the Russell Senate Office Building.

Spermatagonial stem cells can be directly converted into other cell types

Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. Their approach, described this month in the journal Stem Cells, may prove to be an effective alternative to the medical use of embryonic stem cells.

Scientists create baby mice from mouse stem cells

In groundbreaking research scientists from China have for the first time created baby mice by using powerful stem cells from adult mouse skin.

Bones from stem cell technology

Scientists are closer to understanding how to grow replacement bones with stem cell technology, thanks to research published today in the journal Nature Materials.

Embryonic stem cells used to create human sperm

Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility.

Research may hold key to maintaining embryonic stem cells in lab

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.

Family Research Council President says NIH stem cell guidelines ethically irresponsible

Today, Family Research Council President Tony Perkins responded to the National Institutes of Health (NIH) guidelines implementing President Obama's executive order for federal funding of human embryonic stem cell research (ESCR). President Obama's order and the NIH guidelines remove life-protecting limits on federal funding of embryonic stem cell research.

Obama administration releases final rules on stem cell research

The Obama administration released final regulations governing stem cell research on Monday. The New York Times reports that the rules will allow many older stem cell lines to be eligible for federally financed research.

Bioethicists lead call for public debates on future uses of stem cells

More than 40 scientists, bioethicists, lawyers and science journal editors are calling on their colleagues, policy makers and the public to begin developing guidelines for the research and reproductive use of stem cell-derived eggs and sperm, even though such use may be a decade or more away.

Scientists edit genes in human stem cells

Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies. Reporting this week in Cell Stem Cell, the team altered a gene responsible for causing the rare blood disease paroxysmal nocturnal hemoglobinuria, or PNH, establishing for the first time a useful system to learn more about the disease.

Scientists create pig stem cells

Scientists have managed to induce cells from pigs to transform into pluripotent stem cells - cells that, like embryonic stem cells, are capable of developing into any type of cell in the body. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves (known as ungulates).

Protein abundant in embryonic stem cells offers a new cancer target

A protein abundant in embryonic stem cells is now shown to be important in cancer, and offers a possible new target for drug development, report researchers from the Stem Cell Program at Children's Hospital Boston.

Combination of gene therapy and induced pluripotent stem cells cure human genetic disease in vitro

A study led by researchers at the Salk Institute for Biological Studies, has catapulted the field of regenerative medicine significantly forward, proving in principle that a human genetic disease can be cured using a combination of gene therapy and induced pluripotent stem (iPS) cell technology. The study, published in the May 31, 2009 early online edition of Nature, is a major milestone on the path from the laboratory to the clinic.

Researchers discuss combined approach to maximize benefits and minimize risks of stem cell therapy

Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician.
