Herein we show an accessible technique based on Faraday waves that assist the rapid assembly of osteoinductive β-Tricalcium phosphate (β-TCP) particles as well as human osteoblast pre-assembled in spheroids. The hydrodynamic forces originating at 'seabed' of the assembly chamber can be used to tightly aggregate inorganic and biological entities at packing densities that resemble those of native tissues. Additionally, following a layer-by-layer assembly procedure, centimeter scaled osteoinductive three-dimensional and cellularized constructs have been fabricated. We showed that the intimate connection between biological building blocks is essential in engineering living system able of localized mineral deposition. Our results demonstrate, for the first time, the possibility to obtain three-dimensional cellularized and acellularized anisotropic constructs using Faraday waves.
在此,我们展示了一种基于法拉第波的可及技术,该技术有助于快速组装具有骨诱导性的β-磷酸三钙(β-TCP)颗粒以及预先组装成球体的人成骨细胞。源自组装腔室“海床”的流体动力可用于以类似于天然组织的堆积密度紧密聚集无机和生物实体。此外,按照逐层组装程序,已制造出厘米级的具有骨诱导性的三维细胞化构建体。我们表明,生物构建块之间的紧密连接对于构建能够进行局部矿物质沉积的生命系统至关重要。我们的结果首次证明了利用法拉第波获得三维细胞化和非细胞化各向异性构建体的可能性。
