Scientists use these samples to develop everything from flu vaccines to penis-enlargement products. They put cells in culture dishes and expose them to radiation, drugs, cosmetics, viruses, household chemicals, and biological weapons, and then study their responses. Without those tissues, we would have no tests for diseases like hepatitis and HIV; no vaccines for rabies, smallpox, measles; none of the promising new drugs for leukemia, breast cancer, colon cancer. And developers of the products that rely on human biological materials would be out billions of dollars.
