BACKGROUND:Along with the increasing improvement of bladder tissue engineering research, the vascularization of tissue-engineered bladder after implantation becomes an issue of concern. OBJECTIVE: Combined with relevant literature in recent years, to review the choice, design and application of scaffold materials for bladder tissue engineering as wel as vascularized strategies folowing implantation. METHODS:The first author retrieved PubMed database and CNKI databases for articles relevant to biological scaffold materials in bladder tissue engineering and vascularization of tissue-engineered bladder published between January 2000 to September 2014 using the keywords of “tissue engineering; bladder; biomaterials/scaffolds; vascularization” in English and Chinese, respectively. RESULTS AND CONCLUSION: Recently, the biological scaffolds for bladder tissue engineering include two main categories: natural biomaterials and synthetic polymers. The major target of bladder tissue engineering remains to prepare the best cel-seeded scaffolds, to determine the best source of stem cels, to explore the best differentiation way of stem cels, and to promote angiogenesis and nerve regeneration of implanted scaffolds. Thereinto, promoting vascularization of scaffold materials and building complex tissues is most chalenging. At present, it is stil difficult to precisely control the directional proliferation, migration and differentiation of the attached endometrial cels. Although the vascular network is necessary for the nutrient supply and metabolic waste removal of cels or tissues, strategies to promote angiogenesis or vasculogenesis are stil limited.
