Abstract :

Tissue engineering aims at integrating cells, growth factors, tissues, material engineering to produce the best substitutes for organ transplantation. When it comes to valve replacement surgeries, Mechanical heart valves had always been cost effective and commercially successful but they show complications like thromboembolism, hemorrhage, imperfect hemodynamic performance and prosthetic endocarditis. To overcome the complications, increasing number of devices is being designed from biological scaffolds, like Decellularized Bovine pericardium, porcine valves tissues. The most important part of using a Xenograft for surgery is the processing technique employed. There had been lot of failures so far in using the tissue engineered scaffolds, like Ionescu-Shiley valves due to the problem with the decellularisation and stabilization protocols. There are effective decellularisation protocol employing Detergents and enzymes. Though, decellularisation is carried out properly, cell attachment may be difficult many times due to intact collagen matrices and low cell adherence spaces. In this study, we try to find out the effects of mechanical forces on the decellularised scaffolds that cause minimal damage on the extracellular matrices and create gaps within adjacent collagen bundles for cell attachment. We have subjected the xenograft scaffold to waterbath sonicator for particular time at specific conditions. The resulting scaffold was thinner, easy to handle and the H&E staining showed the scaffolds to have enough spaces among large collagen bundle enabling easy cell adherence. This scaffold can enhance cell adhesion and growth, which has always been a challenging task in the field of regenerative studies. Recent Publications: 1. John C. Fitzpatrick, Peter M.
