I don't think that the main problem is the regulation. The regulations are a side effect of how difficult and harmful these experiments could to humans. In the software business when a project fails we can just used a starting point for the next iteration. In life sciences they don't have that luxury. There is no way to test something quickly (in seconds and minutes). May be one day we'll have a complete model of the human body and medicine and drugs can be tested through a software.
