However, tissue scaffolds are non-autologous, consisting of metals, cements, polymers, and animal tissues with a confined biocompatibility and application. Therefore, this study presents a processing method to generate an autologous tissue scaffold from albumin, the major protein in mammalian blood. Albumins were polymerized into an albumin polymer by microbial transglutaminase, and further processing by freeze-drying molding to form an albumin tissue scaffold. Scanning electron microscopy and material testing analyses demonstrated that albumin tissue scaffold has porous structure, moderate mechanical strength, and resilient property. Using three-dimensional (3-D) tissue culture of rat mesenchymal stem cells (MSCs) as a model, we will test their biocompatibility, cell differentiation and possible clinical applications. During the 2nd year’s project, we will perform the animal study on nude mice, autognous albumin scaffold animal study on Witar rat, allogenous albumin scaffold animal study on Witar rat and then xenogenous albumin scaffold animal study on Witar rat. To expand its possible clinical apllictions. During the 3rd year’s project, the possible applications on Larger animla (such as Pig or sheep) will be performe and then preparation for human study will be arranged.白蛋白自體移植再生醫學幹細胞組織載體組織工程AlbuminAutograftRegenerative medicineStem cellsTissue scaffoldTissue engineeringBlood-Derived Tissue Scaffold for Artificial Autograft Fabrication (I)
