Researchers grow stem cells from human skin

...the cells have potential to be used both in tissue engineering ?the science of growing tissues and organs in the laboratory ?as well as in cell therapy. For cell therapy, laboratory-grown cells would be injected into the body to replace breast tissue removed by surgery, to fill in the gaps in bone fractures or r...

When it comes to cell entry, being average has its advantages

... to keep them out," said L.B. Freund, professor of engineering at Brown. "Or if you do want molecules to get in ?those in medication, say ?knowing an optimal particle size for entry is also helpful. "With nanotubes, we may be able to manufacture ones of a certain size to minimize chances that they'll enter and ...

Self-assembled DNA buckyballs for drug delivery

...ssistant professor of biological and environmental engineering in whose lab the DNA structures were made, suggests that drugs could be encapsulated in buckyballs to be carried into cells, where natural enzymes would break down the DNA, releasing the drug. They might also be used as cages to study chemical reacti...

Bacteria are key to 'green' plastics, drugs

...SBS550MG -- contains an ingenious bit of metabolic engineering that allows it to produce succinate in two different ways. One method exists in wild strains of E. coli and has been modified with the deletion of four genes, each of which codes for a protein that interferes with or limits E. coli's ability to turn ...
