Tissue Engineering News and Research

RSS

Dramatic advances in the fields of biochemistry, cell and molecular biology, genetics, biomedical engineering and materials science have given rise to the remarkable new cross-disciplinary field of tissue engineering. Tissue engineering uses synthetic or naturally derived, engineered biomaterials to replace damaged or defective tissues, such as bone, skin, and even organs.

Lithuanian researchers use freeze-drying technique to create sponge-like wound dressings

Group of researchers at Kaunas University of Technology, Lithuania are developing new generation sponge-like wound dressings with hyaluronic acid. Antimicrobial, antioxidant, anti-inflammatory wound dressings stimulate tissue regeneration and can be especially efficient in treating deep wounds that are difficult to heal.
