Sparing The Lab Rat

George Dvorsky reports on new technologies that could eliminate the need for animal testing:

Take research laboratory CeeTox, for example. They're using human cell-based in vitro (lab grown) models to predict the toxicity of drugs, chemicals, cosmetics, and consumer products — tests that are replacing the need to pump potentially hazardous chemicals into animals' stomachs, lungs, and eyes. Likewise, biotech firm Hurel has developed a lab-grown human liver that can be used to break down chemicals. There's also MatTek's in vitro 3D human skin tissue that's being used by the National Cancer Institute, the U.S military, private companies, and a number of universities. Their virtual skin is proving to be an excellent substitute for the real thing, allowing scientists to conduct burn research, and to test cosmetics, radiation exposure, and so on.
