Provocative title* but otherwise interesting and important work. There have been a few developments in recent years to replace stages of animal testing with tissue engineering constructs. There are even prizes: http://www.nc3rs.org.uk/page.asp?id=1740

They're not without limitations though. Testing a drug intended for treatment of a liver condition on a tissue construct is all well and good unless you miss out that there are side effects on other tissue types. There's also a lot of work ahead as there will be limited crossover between different types of tissue construct. All said it's still very exciting work.

*Implies limited input from biologists, that few are working on it, that the whole process of drug testing will be changed rather than an alteration to the pre-animal and animal-stages etc.
