Tissue engineering typically requires a use of scaffolds when delivering tissue-specific cells to be engineered. Hydrogels are frequently used as scaffolds, because their composition, structure, and function resemble the natural tissue extracellular matrix. In this study, hyaluronate-alginate hybrid (HAH) was
