Currently costs $1 billion for every new drug which is approved for market.
Pharmaceutical companies rely heavily on animals (often rodents) to test efficacy and safety of potential drugs.
Many chemicals which show promise in animal studies fail to work in human trials – these “false starts” increase the cost of drug development.
We may also miss potentially useful drugs because they fail to work in rodents.
Tissue engineering is the growth of functional organs from human cells in the laboratory.
Engineered tissue allows us to test potential drugs in a functional human organ.
Testing drugs in human organs will increase the efficiency of drug development by ensuring drugs work in the target organ before human clinical trials.
Engineered human organs will reduce the need for animal testing.
