Immune Response To Human Embryonic Stem Cells In Mice Suggests Human Therapy May Face Challenge

Human embryonic stem cells trigger an immune response in mice, researchers from the Stanford University School of Medicine report. The finding suggests that the effectiveness of human therapies derived from the cells could be limited unless ways are found to dampen the rejection response.

Injections To Replace Heart Surgery?

chareverie writes "Researchers at Harvard University have been working towards a goal of replacing some types of heart surgery with injections of cells that would grow into blood vessels for damaged hearts. The cells that would be used are progenitor cells obtained from the blood or bone marrow, as opposed to stem cells that are obtained from human embryos. The research team was successful with their tests on growing heart blood vessels in mice. Joyce Bishoff, an associate professor of medicine at Harvard and senior author of the report, says, 'Our next goal down the line is to use them in humans.' She also notes that more studies need to be done on animals to see how these cells would react and behave with other types of tissues. A similar human experiment was done two years ago in Germany, during which a few people from a group of 75 he

Comparison of Human T Cell Repertoire Generated in Xenogeneic Porcine and Human Thymus Grafts.

Background. Xenogeneic thymus transplantation is an effective approach to achieving T cell tolerance across highly disparate xenogeneic species barriers. We have previously demonstrated that phenotypically normal, specifically tolerant human T cells are generated in porcine thymic grafts. In this study, we assessed the diversity of the human T cell repertoire generated in porcine thymic xenografts. We also examined the ability of porcine thymus grafts to coexist with human thymus grafts.

UK Approves Human-Pig Embryo Stem-Cell Harvest

An anonymous reader writes "British biologists have received government approval to create the world's first human stem cells from hybrid embryos, part pig, part human. The Warwick Medical School team, led by Justin St. John of the Clinical Sciences Research Institute, was granted the country's third animal-human embryo license from the Human Fertilisation and Embryology Authority, which goes into effect today (July 1)."

'Diablo III' Producer Plays Down 'Too Human' Comparisons (Too Human)

"Both recent and early impressions of Silicon Knights' "Too Human" have said that the upcoming Xbox 360 title's loot, skill tree and combat systems are similar to that of past "Diablo" titles. Some previews even proclaimed that "Too Human" is "Diablo III" before the Blizzard game was even announced.

Cancer Resistance Technique Moves To Human Trials

TaeKwonDood tips us to news that a new cancer resistance treatment is going into clinical trials after being quite successful at eradicating cancer in mice. Researchers discovered that certain white blood cells called granulocytes from cancer-immune mice were able to cure cancer in other mice. Now, doctors are putting out the call for healthy granulocyte donors in order to test how well it works on humans. The article quotes lead researcher Zheng Cui saying, "In mice, we've been able to eradicate even highly aggressive forms of malignancy with extremely large tumors. Hopefully, we will see the same results in humans. Our laboratory studies indicate that this cancer-fighting ability is even stronger in healthy humans."

Human embryonic stem cells developed from 4-cell embryo; world first may lessen ethical concerns

Barcelona, Spain: For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo, the 24th annual conference of the European Society of Human Reproduction and Embryology heard today (Wednesday 9 July). Dr. Hilde Van de Velde, from the Vrije Universiteit Brussel (VUB), Brussels, Belgium, said that their research meant that it might be possible in the future to produce hESC lines at an earlier stage without destroying the embryo.

Scientists Use Virus To Reprogram Adult Cells In Mice

n2hightech writes "Harvard University scientists figured out how to activate a trio of dormant genes that commanded non-insulin producing pancreas cells to switch to the Beta type insulin producing cells. The method uses an engineered virus to infect the cells and deliver special proteins that activate the dormant genes. This technology has the potential to make all stem cell based methods obsolete because it does not pose the risk of rejection and cancer associated with stem cells. A simple injection into the area where cells need to be reprogrammed is all that is required." Gospodin adds a link to coverage at the Washington Post.

Analyzing biocompatibility of medical nanotechnology applications with blood

(Nanowerk Spotlight) Any drug intended for systemic administration and all medical devices which will contact blood (e.g. oxygenators, tubing, catheters, artificial hearts) must undergo thorough biocompatibility testing. These tests include an in vitro assay to determine the material's potential to damage red blood cells (hemolysis). Hemolysis, the abnormal breakdown of red blood cells either in the blood vessels (intravascular hemolysis) or elsewhere in the body (extravascular), can lead to anemia or other pathological conditions. In the pharmaceutical industry, hematocompatibility testing is harmonized through the use of internationally recognized standard protocols. ASTM F756 – Standard Practice for Assessment of Hemolytic Properties of Materials – is a widely used standard for blood-damage testing.

Too Human Did Not Take Ten Years

"Too Human's release on the Xbox 360 is edging closer and closer and with that, TGR sat down with Silicon Knights CEO Denis Dyack at this year's E3 to talk about the upcoming release of Too Human. One assumption that everyone makes in regards of Too Human is how long it took to develop, starting on the Playstation 1 and finishing up on the Xbox 360 with ten years of development time. We thought it was about time we got to the bottom of this and asked Denis himself."

Researchers Modify T-Cells, Make Them HIV Resistant

DieNadel writes to share that naturally occurring proteins called "zinc fingers" are being used in a new approach to AIDS treatment. Using modified T-Cells with the zinc fingers, researchers at the Pennsylvania School of Medicine have shown a reduction in viral load in mice. "'By inducing mutations in the CCR5 gene using zinc finger proteins, we've reduced the expression of CCR5 surface proteins on T cells, which is necessary for the AIDS virus to enter these immune system cells,' explains first author Elena Perez, MD, PhD, Assistant Professor of Pediatrics at Penn. 'This approach stops the AIDS virus from entering the T cells because it now has an introduced error into the CCR5 gene.'"
