- In an attempt to integrate engineered tissue with native tissue, three samples of engineered tissue, X, Y, Z, with identical material properties, were co-cultured adjacent to three different native tissues (bone, cartilage and liver). The adhesive strengths of X, Y, Z were observed after 8 weeks as follows.
Adhesive strength for X = 150 kPa, Y= 250 kPa, Z= 350 kPa
Match the native tissue that were used to co-culture X, Y and Z from the following.
I : Liver Tissue
II : Articular Cartilage
III: Devitalized Bone- GATE BM - 2024
