Scientists create 3D-printed bone repair scaffolds using marine collagen and fish-derived minerals, showing improved cell growth.
A group of scientists have developed 3D printed scaffolds made out of marine collagen and fish bone minerals to aid in bone regeneration. The scaffolds, meant to underpin personalized treatments, proved effective in laboratory tests.
It mixes collagen from the marine sponge Chondrosia reniformis with calcium phosphates derived from fish bones of the cod type. Strontium was supplemented to facilitate cell proliferation. The perfectly porous and strong nature of 3D-printed structures in bone repair is a core point.
In lab tests, human bone cells grown on the scaffolds showed increased viability over two weeks. The approach aligns with sustainable practices, using marine resources for medical applications.

The study, published in a scientific journal, could lead to new treatments for bone defects. Further testing is needed before clinical use.
