Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...earchers 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. Their paper calls it "the first demonstration that human umbilical cord blood-derived stem cells can be engineered" to synthesiz...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...dies, his group successfully demonstrated that the caps can be chemically activated to pop open and release the cargo inside of animal cells. This unique feature provides total control for timing the delivery The team’s first attempt to use the porous silica nanoparticle to deliver DNA through the rig...

Short chromosomes put cancer cells in forced rest

...f white blood cells. Telomerase helps maintain the caps or ends of chromosomes called telomeres, which shrink each time a cell divides and eventually - when the chromosomes get too short - force the cell to essentially commit suicide. Such cell death is natural, and when it fails to happen, the result ma...

Osteoarthritis may be sign of faster 'biological ageing'

...l shortening of telomeres, the length of DNA which caps the tips of chromosomes. A host of factors make them shorten over time, including insufficient repair of the damage caused by oxygen free radicals (oxidative stress). Oxygen free radicals are the unstable molecules produced as a by-product of norma...

Aging cells, aging body: Fresh evidence for a connection

... structures signals that the protective chromosome caps called telomeres have dwindled enough to halt cell division. Scientists painstakingly counted the cells with aging biomarkers. What they found: The number of senescent cells increased exponentially with age. TIF-positive cells made up about 4 percen...

Rice bioengineers pioneer techniques for knee repair

...s ago that we would be making entire articular end caps via self assembly I would have said you were crazy," said Athanasiou. "The fact that we can do this is an indication of how far the discipline of tissue engineering has progressed." Unlike cartilage, most tissues in our bodies ?including skin, blood...

Scientists map one of biology's critical light-sensing structures

...ing first author graduate student Jeremiah Wagner, caps a 30-year quest by biologists to drill down to the inner workings of how plants, fungi and bacteria use light to guide their development. It will likely spur a rush by scientists to capitalize on the new knowledge and may one day lead to such things...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...suring impacts of climate change and, should polar caps continue receding, hypothetical new disturbances on the northern ocean such as energy exploitation, fishing and shipping. The research compares species distribution in the shelf, slope and deep sea regions (the deep sea is generally agreed to begin ...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

... on the ends of chromosomes that act as protective caps -- allowing DNA ends to be copied completely when cells are replicated. This is the first major piece of telomerase for which the structure is known. Telomerase plays a key role in most cancers, and this work ultimately may lead to targets for drug ...
