<p>Advances in organ and computer models are raising the prospect that some animal experiments could be eliminated. But there are still huge hurdles to overcome</p>
Organ-on-a-chip technology involves creating miniature organs on a microchip that mimic the functions of real organs. This technology allows for more accurate testing of drugs and diseases without the need for animal testing.
In silico models are computer-based simulations that are used to predict biological responses and outcomes. These models can significantly reduce the need for animal experiments by providing a virtual environment for testing.
