- 요약Background: Ischemic heart disease is the leading cause of death worldwide. Cardiac patch-based regenerative therapies have shown great promise in the treatment of myocardial infarction (MI). The clinical applications of patch devices, however, face major limitations mainly due to the inadequate integration of typically nonvascular implanted grafts with the recipient heart muscle tissue, the lack of patient and damage specificity, and insufficient perfusion. Further, there is a critical need for nondestructive imaging techniques that enable precise, quantitative monitoring of the cardiac patch function following implantation. 3D Bioprinting is revolutionizing the fields of personalized and precision medicine by enabling the manufacturing of bioartificial constructs that closely recapitulate the structural and functional characteristics of native tissues/organs. Particularly in cardiovascular regenerative medicine, bioprinted tissue constructs have demonstrated great potential as medical patch devices in repairing damaged or diseased heart tissue.Approach: Using multi-material 3D bioprinting, functional nanomaterials, and photon counting computed tomography (PCCT) technologies, this project developed a new precision medicine approach to custom-engineer patient and damage-specific vascular patch devices with PCCT visibility. The hypothesis is that cardiac patch devices with customized architecture and vasculature can be fabricated to closely correspond to those of the recipient heart tissue and be incorporated with multiple contrast agents to longitudinally track various functions of the patch. Aim 1 sought the design and development of traceable vascular patch devices and their evaluation both in vitro and in vivo. Aim 2 assessed the design of a vascular network within the patch, its endothelialization, and in vitro imaging properties in static versus flow culture conditions. Aim 3 investigated the function of the bioprinted vascular cardiac patch in vivo. Multiple PCCT-visible cardiac bioinks, consisting of distinct contrast agent-laden hydrogel formulations, were used to bioprint patch structures that closely correspond with the geometry of the target MI tissue. PCCT distinguished multiple contrast agents to assess patch surgical location, integration and degradation, and perfusion, both in vitro and in a rat model of MI. In summary, establishing this novel, high-fidelity, theranostic platform with remarkably high precision, tunability, and reproducibility would be paradigm changing and open new prospects for a broad range of tissue engineering applications.
