This chapter introduces the volume Collaborative Bioethics: Regenerative Medicine and the Bioethics of Globalization, Justice and Hegemony. It outlines the central themes of the collection, including global asymmetries in regenerative medicine research, epistemic injustice, and the need for inclusive and context-sensitive ethical governance. The chapter also summarizes the contributions in the volume, which collectively examine the ethical, legal, and social dimensions of regenerative medicine across diverse national and regional contexts.
