Researchers at Stony Brook University developed TRACE (Tunable Rapid Assembly of Collagenous Elements), a novel collagen bioprinting method enabling instant assembly of physiological collagen constructs with high biocompatibility and rapid gelation. This technique facilitates structural complexity and biofunctionality, potentially transforming tissue engineering, drug development, and regenerative medicine. Concurrently, a team reported a minimal model mimicking extracellular matrix assembly via controlled phase separation, offering insight into natural tissue scaffold formation mechanisms.
