We are pleased to invite you to join us for the 11th edition of COSTEM, the Congress on Controversies in Stem Cell Transplantation and Cellular Therapies, taking place October 1–4, 2026, in Berlin, Germany.

COSTEM 2026 will continue to serve as a dynamic platform for our community to engage, collaborate, and exchange the latest scientific research, clinical advancements, and emerging developments in the field. The Congress is built around interactive debate sessions in which global experts present and challenge perspectives on a wide range of critical issues. This distinctive format provides clinicians with an exceptional opportunity to share insights, compare experiences, and explore innovative strategies aimed at improving patient care.

This upcoming edition promises to deliver a progressive, thought-provoking, and highly informative experience. By addressing the most significant and controversial topics shaping the field today, COSTEM 2026 will foster meaningful dialogue, ongoing learning, and professional growth.

We warmly encourage you to join us in Berlin for what will be an inspiring gathering of experts, researchers, and clinicians. Your participation will enhance the discussions and further support the advancement of our shared mission.
