组织移植手术治疗小儿先天性心脏病是一种挽救生命的干预。脱细胞以降低组织移植物的免疫原性是戊二醛固定的一种越来越受欢迎的替代方法。在这里,我们提出了一种使用3D打印流动室使猪右心室流出道去细胞化的方案。我们描述了3D打印流动装置、制备猪组织以及使用流动装置利用剪切力进行去细胞化的步骤。然后,我们详细描述了表征脱细胞支架的程序。关于该方案的使用和执行的完整细节,请参考Vafaee等人1。
Surgical treatment of pediatric congenital heart disease with tissue grafts is a lifesaving intervention. Decellularization to reduce immunogenicity of tissue grafts is an increasingly popular alternative to glutaraldehyde fixation. Here, we present a protocol to decellularize porcine right ventricular outflow tracts using a 3D printed flow chamber. We describe steps for 3D printing the flow rig, preparing porcine tissue, and using the flow rig to utilize shear forces for decellularization. We then detail procedures for characterizing the acellular scaffold.For complete details on the use and execution of this protocol, please refer to Vafaee et al.1
