I've heard from animal rights activists that experiments on animals are not necessary because we can get the same or better results from cell culture experiments.
An example of that claim is this excerpt from a comment on a blog:
2) According to the former scientific executive of Huntingdon Life Sciences, animal tests and human results agree “5%-25% of the time.”
3) Among the hundreds of techniques available instead of animal experiments, cell culture toxicology methods give accuracy rates of 80-85%
I don't want to focus on the exact numbers given here, but on the general issue of toxicology testing using animals and cell cultures. Determining the safety of new chemical compounds, drugs etc. is a major use of animal experiments, I'll focus my question on these toxicological studies.
Can cell culture methods effectively replace animal experiments for toxicological studies?
