Kind: research · Impact: medium

## In brief

- Chen et al. describe a sliding annular in situ bioprinting strategy for small-diameter vascular grafts.
- The method combines a detachable annular printhead, PH hydrogel, and a sacrificial PVA scaffold.
- In a rabbit carotid artery model, the strategy reportedly restores blood flow and supports repair.

## Why it matters

It proposes a way to fabricate small-diameter vascular grafts directly at the repair site, which could matter for regenerative medicine and tissue engineering research.
