Jellyfish collagen bioink revolutionizes 3D-printed skin regeneration

Researchers from Immanuel Kant Baltic Federal University have developed a new bioink for 3D bioprinting. The innovation uses marine collagen and has been officially patented. It offers a promising solution for skin regeneration in medical treatments. The bioink’s main ingredient is collagen extracted from the jellyfish Aurelia aurita. This marine collagen supports skin healing and carries a lower risk of allergic reactions than animal-based alternatives.

When mixed with sodium alginate, the bioink forms a soft hydrogel that closely mimics living tissue. Scientists can use a 3D bioprinter to create skin structures with it. Tests show it boosts the growth and division of human skin cells by 40 to 50 percent.

The new material also speeds up patient recovery. It reduces the likelihood of secondary infections during the healing process. The patented bioink combines marine collagen with advanced printing technology. It improves skin cell growth and aids faster rehabilitation. Its low allergenic properties make it a safer option for medical applications.
