All blood vessels are specifically structured to perform their function. For example, a capillary is microscopically thin to allow gases to exchange, the arteries are tough and flexible to cope ...

However, existing BBB models have been unable to replicate the complex three-dimensional 3D structure of cerebral blood vessels, posing significant challenges for research and drug development.

Zhu explained that the issue with existing grafts is that they cannot fully replicate how our blood vessels respond to stress and movement. "That's the reason we want to introduce this structure.
