Startup aims to grow 'organ sacks' for testing

Biotechnology startup R3 Bio is developing a novel approach to replace animal testing by engineering 'organ sacks.' These are described as genetically modified whole organ systems designed without a brain. The company's long-term vision extends to creating human versions of these organ systems. This innovative research aims to provide a more ethical and potentially more accurate alternative to traditional animal testing methods in scientific research and drug development. The development signifies a significant step towards more advanced and humane biological modeling for various applications.
