摘要:
A bona fide adaptable in vitro microcirculation model is provided by integrating a 3-D printed network of endothelial-cell lined perfusion channels, formed via sacrificial casting in a gel matrix, with a native, adaptable microvasculature matured from native microvessels added to the gel matrix. Responsive vascular adaptation exhibited by the in vitro microcirculation is physiologically relevant. Methods for fabricating, devices, models and investigative platforms for pharmaceutical applications, vascular mechanism and microvessel-parenchyma interaction studies, and vascularizing strategies for tissue engineering applications are also disclosed.
摘要:
A bioassembly system having a tissue/object modeling software component fully and seamlessly integrated with a robotic bioassembly workstation component for the computer-assisted design, fabrication and assembly of biological and non-biological constructs. The robotic bioassembly workstation includes a six-axis robot providing the capability for oblique-angle printing, printing by non-sequential planar layering, and printing on print substrates having variable surface topographies, enabling fabrication of more complex bio-constructs including tissues, organs and vascular trees.
