During the past decade, more than 100 hand and facial transplants have been performed around the world, including over 90 with encouraging outcomes. Title 3D Video Augmented High-Resolution Ultrasound Imaging for Monitoring Nerve Regeneration and Chronic Rejection after Composite Tissue Allotransplantationĭescription: This technology has direct relevance to the FY13 PRMRP topic area of Composite Tissue Transplantation. PI Vijay Gorantla, John Galeotti, George Stetten If a newly functional tissue can be generated to replace that which is lost due to the stroke, this approach could indeed dramatically change the long-term outcome after stroke. The proposed studies aim to address these challenges and provide a framework within which we can eventually explore the therapeutic potential of this approach.
Very significant technological, as well as neurobiological challenges, however, need to be addressed before we can integrate this multi-parametric MRI into an efficient non-invasive assessment of in situ tissue engineering. Our proposal here aims to develop chemical exchange saturation transfer (CEST), a non-invasive MRI technique, as a core platform to visualize multiple cell types, as well as biomaterials, while maintaining our ability to characterize newly forming tissue with other MRI techniques, such as MRS, as well as diffusion and perfusion MRI. Translation of this non-invasive monitoring into patients requires the development and implementation of appropriate approaches.
As stem cells are integrated with biomaterials for in situ tissue engineering, the complexity of the procedure is increasing and it is becoming important to monitor how these processes interact over time in vivo.
