Saving and improving lives by catalyzing the world’s transition to human-specific medical research. Human biology-based methods offer a more effective way to understand the diseases that afflict us. And they enable researchers to predict how a human may respond to medicines and chemicals with far greater accuracy than animal tests. The outcome is better treatments, therapies, and cures. CCS is pioneering a paradigm shift towards innovative, evidence-based research methods that are based on human biology. Through collaboration, we champion technologies that are better for humans and that replace animal testing.
