Tissue engineered vascular graft

The complication that halted a clinical trial for tissue-engineered vascular grafts for children with congenital heart disease may reverse spontaneously without clinical complications. Based on promising laboratory and animal modeling of a biodegradable scaffold seeded with a patient’s own cells, a clinician-scientist research team now based at Nationwide Children’s Hospital initiated a pediatric tissue engineered…

Using Computer Models to Predict How Tissue Engineered Vascular Grafts Will Work 150 150 Kevin Mayhood

Model and experimental data strongly suggest testing TEVGs until scaffold has biodegraded Identical tissue engineered vascular grafts (TEVGs) being tested in small-diameter veins and arteries of a mouse model performed well for 12 weeks. At 14 weeks, all TEVGs in the veins continued performing well, but all in the arteries suddenly failed. During their effort to understand…

Why Do Synthetic Tracheal Replacements Fail?
Why Do Synthetic Tracheal Replacements Fail? 150 150 Lauren Dembeck

Synthetic tracheal replacements experience infectious, inflammatory and mechanical failures. Tracheal defects in children and adults can often be addressed with current surgical techniques. However, when a defect is large, greater than 50% of an adult windpipe or 30% of a pediatric windpipe, few options exist to repair it without donor tissue. For decades, tissue engineers…

From What-if to Widely Available – A Proposed Path for Tissue Engineered Vascular Grafts
From What-if to Widely Available – A Proposed Path for Tissue Engineered Vascular Grafts 150 150 Abbie Roth

What if you could utilize tissue engineering, imaging and 3D printing technologies to bring the benefits of a tissue engineered vascular graft to every child who needs one? Children born with a single ventricle heart defect undergo a series of surgeries and procedures to reroute the blood flow through their heart. The Fontan operation is…

Growing Tissue to Help Children With Short Bowel Syndrome 1024 575 Kevin Mayhood

Research using a small animal model shows that it matters where in the body the cultured intestine is grown. Researchers at Nationwide Children’s Hospital are hoping to use short bowel syndrome patients’ own cells to grow extra tissue needed for their small intestine to function properly. Using rat models, the team of physician-scientists found that…

Tissue engineered vascular graft

Seeding a high number of bone marrow mononuclear cells on graft appears to prevent narrowing. Tissue-engineered vascular grafts hold promise for children with congenital heart disease because the grafts, which carry a patient’s own cells, have the potential to grow and regenerate just as the child’s blood vessels do. But over time, some grafts develop…
