Biodegradable polyurethane scaffolds for tissue engineering

摘要

Combined phase-inverse - salt leaching technique allows for the preparation of 3-D microporous biodegradable polyurethane scaffolds with controlled pore sizes and pore-to-volume ratios. The scaffolds have good mechanical properties and undergo elastic recovery under loading. MTT cytotoxicity tests have shown that these scaffolds are noncytotoxic and may be promising candidates for tissue repair and regeneration.
