Research teams from École Polytechnique Fédérale de Lausanne , cooporated to create a new hydrogel material that can heal the ” Damaged cartilages ” .
Whats a Cartilage ?
Cartilage is a tough and flexible form of connective tissue and can be also considered as modified connective tissue . there is a lot of cartilage types , Like the Hyaline cartillage wich is the most common and found in joints , also the elastic cartilage wich is found in the epoglottis and the ears , and the fibrocartilage wich is found in the fibrosis of intervertabral disk and the menisci of Knee .
As we all know , Cartilage isn’t like other soft tissue damage . It doesn’t heal itself and usually reuires a medical intervention .
And that’s why the hydrogel material comes in , as it can be easily loaded with other drugs or reparing cells .
The use of hydrogel would drastically improve healing these injuries simply because of its ability to adhere to tissue in an effective way.
According to Dominique Pioletti, one of the team leaders, this adhering quality comes thanks to hydrogel’s “double network structure” that “distributes incoming mechanical energy throughout.” Essentially, this unique material serves as a perfect vehicle to hold onto cartilage-repairing drugs, while also being able to easily cling to damaged areas.
