Extracellular Matrix Patches for Endarterectomy Repair

Extracellular matrix scaffold for cardiac repair.

BACKGROUND Heart failure remains a significant problem. Tissue-engineered cardiac patches offer potential to treat severe heart failure. We studied an extracellular matrix scaffold for repairing the infarcted left ventricle. METHODS AND RESULTS Pigs (n=42) underwent left ventricular (LV) infarction. At 6 to 8 weeks, either 4-layer multilaminate urinary bladder-derived extracellular matrix or ...

Bioactive Extracellular Matrix Scaffold Promotes Adaptive Cardiac Remodeling and Repair

Use of a small intestine submucosa extracellular matrix patch in repeated carotid endarterectomy.

Various patches have been described in the literature for patients undergoing carotid endarterectomy. In the present report, the authors present the case of a 71-year-old woman who had bilateral carotid endarterectomies 17 years earlier and greater than 80% restenosis of the right internal carotid artery. The patient underwent a repeated right carotid endarterectomy using a small intestine subm...

Reinforcement of a decellularized extracellular matrix-derived hydrogel using nanofibers for cardiac tissue engineering

The role of heart disease in increasing worldwide death and the limited availability of organs for transplantation have encouraged multiple strategies to fabricate functional and implantable constructs. One of these strategies is to develop a biologically similar heart tissue scaffold, in which two types of fiber and hydrogel are commonly used. Toward this goal, taking advantage of both hydroge...

Extracellular Matrix Adjuvant for Vaccines

In 1796, Edward Jenner first used the term, “vaccination,” to describe his studies which used poxvirus derived from lesions in cows to protect humans against infection with smallpox (Barquet & Domingo, 1997). Later, Louis Pasteur demonstrated that animals and people could be protected against disease when administered microbes that had been attenuated to reduce pathogenicity. From this early wo...
