A discovery published in the journal Cell in 2023 promised to change knowledge about bone anatomy. A team led by researcher Anjali Kusumbe announced it had found lymphatic vessels inside bones, the small tubes that transport immune cells and drain fluid from tissues. This discovery contradicted an old idea in biology.
Almost three years later, two independent studies failed to find these lymphatic vessels in bones, strongly contesting the original discovery. The scientific dispute reached Cell itself, which published the criticism of the results alongside the response from the authors of the initial study.
Regenerative medicine is in turmoil due to this controversy, which questions the validity of a discovery that could have significant implications for understanding the immune system and bone regeneration.
