the sheep’s urinary bladder matrix as a potent biological materials resource -an ultrastructural study

background and objectives: biological scaffold resources composed of extracellular matrix (ecm) have been shown to make easy the practical remodeling of various tissues in both animal and human studies. the goal of current study was to make sheet form of ecm from sheep’s urinary bladder. methods: ecm was extracted from sheep’s urinary bladder according to standard method. scanning electron microscopy (sem) was applied in order to analyze the ultrastructure of the extracted matrix. results: matrix was formed by irregular and fiber like particles. conclusion: sheep’s urinary bladder matrix may be used as an accessible and suitable source of ecm extraction.
