For instance, according to PETA scientists at Harvard’s Wyss Institute are using in-vitro testing as a replacement for animal models and costs have reduced from $32,000 to $11,000. Because the animal models used to develop medicinal drugs are not predictive of the human situation, in-vitro testing is more suitable since it contains human cell cultures, which best fits human circumstances. This option of implementing human-related tests makes data more reliable and accurate. Also, utilizing substitutes like these are guaranteed to be more cost-effective. Therefore, using animals to develop certain drugs is unnecessary now that there is a much more innovative way to do
