[Biological supports based on cellulose and soybean for cartilage lesions]

The BIOMAT group of the UPV/EHU has developed a biodegradable gel based on natural materials for use in tissue engineering.

They have developed structures composed of cellulose, gelatin and soy proteins from by-products of the food industry. These obtained supports have high biocompatibility and have highly promising mechanical and biological properties for cartilage regeneration.

As explained in the study they have published, what they have achieved is a biodegradable gel that can be used later by 3D printing. After a cartilage injury, the gel allows the construction of a three-dimensional structure in situ, tailored to each person. This structure would serve not only to support the adhesion and proliferation of cells, but also to feed them. After a while, the structure would biodegrade and disappear, and the injured cartilage would be regenerated.

The researchers note that cellulose strengthens the structure and gives it rigidity and tensile strength. Soy protein helps to maintain consistency and gelatin serves as a nutrient for the cells. This study has shown that even using natural materials, very good solutions can be obtained.
