Abstract: Objective: To find out the best way for decellularization and cross-linking of naturally derived bovine pericardiumto prepare GBR membrane which can meet the clinical demand. Methods: Natural bovine pericardium were decellularized using trypsin+ detergent method (I), trypsin +enzymatic nucleic acid method (II), trypsin+ detergent +enzymatic nucleic acid method (III), freeze- thaw+detergent method (IV), freeze-thaw + enzymatic nucleic acid method (V), or freeze- thaw+detergent + enzymatic nucleic acid method (VI), and then were cross-linked using glutaraldehyde or genipin. The best way of decellularization and cross-linked method were screened by means of optical microscope, scanning electron microscope, cell toxicity test, determination of the mechanical properties, and measurement of the chemotactic properties. Results: Freeze- thaw+detergent + enzymatic nucleic acid method with bovine pericardium was the best method of decellularization. Genipin crosslinking method by which acellular bovine pericardium was crosslinked was better. Conclusion: Freeze- thaw+detergent + enzymatic nucleic acid method and genipin crosslinking method were ideal method for preparation of natural bovine pericardium.
