Source: Lee, Y., et.al. Transplantation of Schwann Cells Inside PVDF-TrFE Conduits to Bridge Transected Rat Spinal Cord Stumps to Promote Axon Regeneration Across the Gap. J. Vis. Exp. (2017)This video demonstrates the use of a piezoelectric polymer conduit seeded with Schwann cells to promote axon regeneration in a transected rat spinal cord. The conduit provides structural guidance, while its bioelectric properties stimulate neurite outgrowth. Schwann cells within the conduit secrete...

Blood exposure to polymeric blood conduits initiates the foreign body reaction that has been implicated in clinical complications. Here, the Chandler Loop Apparatus, an experimental tool mimicking blood perfusion through these conduits, is described. Appendage of recombinant CD47 results in decreased evidence of the foreign body reaction on these conduits.

We describe a novel intrathoracic esophagogastric anastomotic technique designed to create a large diameter anastomosis while simultaneously maintaining conduit blood supply to minimize the incidence of anastomotic leaks and strictures. Construction and orientation of the stomach conduit designed to optimize upper gastrointestinal tract function is also described.

To replicate laboratory settings, online data collection methods for visual tasks require tight control over stimulus presentation. We outline methods for the use of a web application to collect performance data on two tests of visual attention.
FAQs
A visible dye acts as a moving marker within an enclosed pathway. By following where it travels, researchers can infer flow direction and identify whether separate sections are connected. The observed route also provides evidence about conduit geometry, while the timing of dye movement helps estimate residence time. This makes tracer observations useful where direct inspection is limited.
The timing of dye arrival and passage indicates how long material remains within a pathway before moving onward. In environmental systems, that information helps distinguish rapid transport from slower movement and supports interpretation of pollutant travel through drainage networks, groundwater pathways, or stormwater infrastructure. It adds a time dimension to spatial mapping and flow analysis.
Physical mapping records the arrangement of conduits, whereas imaging or tracer observations show how material actually moves through that arrangement. Comparing the two can reveal connected routes, flow direction, and differences between an expected network and observed transport. This distinction matters because a mapped pathway may not represent the route followed by water, air, sediments, or contaminants.
Researchers first establish a physical representation of the relevant pathway or network. They then introduce a visible dye and track its movement through the system. The observations are interpreted for route, flow direction, connectivity, and timing. This workflow can be applied to natural pathways or built infrastructure, providing evidence for subsequent assessment and modeling.
Conduit visualization is useful for assessing drainage networks, groundwater pathways, stormwater infrastructure, and pollutant transport. In engineering, the resulting observations can support flow modeling, leak and blockage detection, and system design. In environmental management, they provide evidence for evaluating how water, sediments, air, or contaminants move through natural and built systems.
Observed conduit geometry, connectivity, flow direction, and residence time provide evidence for representing transport pathways in flow models. The same information can help identify leaks or blockages, evaluate drainage and stormwater behavior, and inform system design. For environmental management, these findings support decisions based on observed movement rather than assumptions about how a network functions.
