The experimental characterization of a sample or sub-set of cancer cells from a patient provides totally inadequate information to satisfy the condition of Comprehensiveness.
We need a higher-level theory of cancer based not on the properties of particular cancer cells, but rather based on the properties of the set of all malignant cells that could evolve.
Very little can be known about the set of all malignant cells that could evolve.
The required cell population that must be targeted (killed or controlled) to cure or control cancer, is the set of all malignant cells that could evolve.
Let's be clear: this is not about embryonic stem cell research, which, despite the hype may deliver something given time, although the alternatives of adult stem cells and induced pluripotent stem cells look set to deliver results much quicker.
CNN: Human stem cell cloning: 'Holy Grail' or techno-fantasy?
Spurred by tariff cuts on solar cells, Pittie set up Pittie Renewable Energy Systems in Pune.
That is only a first step, McKay emphasized, a set of directions for creating cells that could be tested as a Parkinson's treatment.
It used a flashlight-like device to activate photo cells on the television set to change channels.
FORBES: Remembering Eugene Polley, an Inventor of the TV Remote
The active ingredient in Rapamune, rapamycin, was discovered decades ago but scientists didn't understand how the drug worked until a graduate student named David Sabatini discovered the mammalian target of rapamycin (mTOR), a protein that acts as part of a complicated set of chemical signals that causes cells to divide.
Change the first set of numbers and you change what the cells do.
Mitochondria, a cell's electrochemical "batteries, " also have genes, left over from when they were bacteria that set up shop inside our distant ancestors' cells.
Though most cells in any individual have the same set of genes, not all of these genes are active in any given cell.
The way in which the cells are interconnected is specified by loading another set of numbers into the chip.
When such a cell divides, at least one of its daughters is also a stem cell (the other may set off on the route to specialisation that allows stem cells to generate new tissue).
His group is especially interested in promoting the technique for treating mitochondrial diseases -- these organelles posses a different set of DNA than that contained in the nucleus of cells, and are responsible for generating the energy needed for cells to function.
Energy deregulation in Europe and America allows new firms to set up cheap, efficient power sources (such as fuel cells) close to the consumer.
During the six years he ran the NIH under George W. Bush, Zerhouni, a pioneering radiologist raised and educated in Algeria, set the first rules for funding research on human embryonic stem cells and banned NIH scientists from taking big industry consulting fees.
Gene therapy, a set of medical technologies that plant new genes in a person's cells in order to produce missing proteins, might be used both to save lives and to ramp up athletic performance.
The firm has set itself the target of cutting costs by the 90% needed to make fuel cells competitive in vehicles by 2003.
The scientists saw that, if these flower-discs were set at a tricky upright angle, the bees much preferred to land on the ones with conical surface cells.
The bioreactor will have to be set up so that a similar volume is pumped through it, but gently to avoid killing the cells.
