Tissue-Engineered Scaffolds for Organ Regeneration
Quick fact
Some scaffolds are 3D-printed from materials designed to degrade into harmless byproducts, and they can even release growth factors at specific times to influence cell behavior.
Why this is interesting
Imagine a building that tells the bricks how to arrange themselves into a house, and then slowly disappears. That's the idea behind tissue-engineered scaffolds, which guide our own cells to rebuild damaged organs.
