Dear friends and colleagues,

we regret to inform you that after careful deliberation the Organising Committee has made a difficult decision to postpone CELLTTS 4 due to the ongoing situation about the current outbreak of COVID-19. We hope to be able to meet you in a fresh, certainly different environment in Sarajevo in 2021. We will keep you informed about the new developments and dates. Stay safe and healthy.

The Organizing and Programme Committees
