60% of people with embryos in U.S. fertility clinics would consider donating them for stem cell research

About 60% of people who have embryos stored at U.S. fertility clinics would be very or somewhat likely to donate them for stem cell research, according to a survey published Thursday in the online edition of the journal Science, Reuters reports (Dunham, Reuters, 6/20).

Senate appropriations committee approves labor-HHS-education spending bill

The Senate Appropriations Committee on Thursday voted 26-3 to approve a $152 billion fiscal year 2008 Labor-HHS-Education appropriations bill after the addition of an amendment that would expand federal funding for embryonic stem cell research, CongressDaily reports (Cohn, CongressDaily, 6/22).

Faster, less expensive technique for mutating large, non-gene stretches of DNA

Genes account for only 2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes, but from mutations of other DNA that controls genes.

Interfacing silicon nanowires with mammalian cells

A research team at the University of California, Berkeley, has achieved a significant step toward one of the futuristic goals of nanomedicine and nanobiology-developing technology for "wiring" together individual cells.

Injected neural stem cells reduce Parkinson's symptoms in primates

Primates with severe Parkinson's disease were able to walk, move, and eat better, and had diminished tremors after being injected with human neural stem cells, a research team from Yale, Harvard, the University of Colorado, and the Burnham Institute report in Proceedings of the National Academy of Sciences.

Researchers reprogram normal tissue cells into embryonic stem cells

Researchers at the Institute for Stem Cell Biology and Medicine at UCLA were able to take normal tissue cells and reprogram them into cells with the same unlimited properties as embryonic stem cells, the cells that are able to give rise to every cell type found in the body.

Funding to upgrade stem cell research facilities at UC San Diego

The University of California, San Diego (UCSD) Human Stem Cell Core Facility, which supports multiple research projects using stem cells to advance the understanding and ultimately the treatment of disease and injury, will receive a $2.8 million Shared Research Laboratory Grant from the California Institute for Regenerative Medicine (CIRM).

Embryonic stem cells can be created without eggs

Embryonic stem cells are unique because they can develop into virtually any kind of tissue type, an attribute called pluripotency.

Ethically universal stem cell lines

Human embryonic stem cells (hESC), those very young cells that are a biological blank slate, have the potential to become more specialized, contributing to the workings of a wide variety of organs and tissues.

Reprogrammed fibroblasts resemble embryonic stem cells

Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.

New platform for regulating the expression of therapeutic genes

A new platform for regulating the expression of therapeutic genes, which will have major implications for gene and cell therapy, was presented at the 10th Annual Meeting of the American Society of Gene Therapy (ASGT) in Seattle.

Researchers engineer adult stem cells derived from human umbilical cord blood to produce insulin

The researchers announced their laboratory finding, which caps nearly four years of research, in the June 2007 issue of the medical journal Cell Proliferation, posted online this week.

Breakthrough in understanding how cancers spread

The University of Manchester study used embryonic stem (ES) cells to investigate how some tumours are able to migrate to other parts of the body, which makes the treatment of cancer much more difficult.

Project aims to develop stem cell lines that genetically match human patients

These lines would allow scientists to better study conditions ranging from diabetes to Parkinson's disease, and they would provide the basis for potential patient-specific stem cell treatments.

Adult stem cells play no role in insulin production

Diabetes researchers, investigating how the body supplies itself with insulin, discovered to their surprise that adult stem cells, which they expected to play a crucial role in the process, were nowhere to be found.

U.S. Supreme Court decision boosts stem cell patent challenge

A U.S. Supreme Court decision in favor of KSR International Corp. on Monday strengthens challenges against overreaching human embryonic stem cell patents held by an affiliate of the University of Wisconsin, the Foundation for Taxpayer and Consumer Rights (FTCR) and the Public Patent Foundation (PUBPAT) said.

Democratic Presidential candidates discuss abortion rights

Eight candidates for the Democratic presidential nomination on Thursday in a debate at South Carolina State University "uniformly criticized" the U.S. Supreme Court's decision last week to uphold a federal law (S 3) banning so-called "partial-birth" abortion, the Washington Post reports (Balz, Washington Post , 4/27).

The convergence of embryonic and cancer signaling pathways: role in tumor cell plasticity

In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells.
