Fig. 6From: Articular cartilage generation applying PEG-LA-DM/PEGDM copolymer hydrogelsUpper row: Macroscopic view of 18 week constructs of ring model for integration study. Below each group are the toluidine blue (left) and collagen type II (right) staining of the integration interface between the engineered cartilage (EC) and native articular cartilage (NC) related to the above constructs.
