Preparation and characterization of human size whole heart for organ engineering: scaffold microangiographic imaging.

Definitive treatment for end-stage heart failure is heart transplantation, however, this is associated with several limitations. We decellularized and assessed ovine hearts through coronary perfusion. To evaluate recellularization, a decellular graft was transplanted hetrotopically into the omental wrap.

Decellularised whole ovine testis as a potential bio-scaffold for tissue engineering.

The aim of this study was to determine an efficient whole-organ decellularisation protocol of a human-sized testis by perfusion through the testicular arteries. In the first step of this study, we determined the most efficient detergent agent, whereas the second phase delineated the optimal time required for the decellularisation process. Initially sheep testes were decellularised by one of three different detergent agents: sodium dodecyl sulphate (SDS), Triton X-100 and trypsin-ethylenediamine tetraacetic acid (EDTA) solutions, each perfused for 6h.

Whole-organ tissue engineering: decellularization and recellularization of three-dimensional matrix liver scaffolds.

To report the results of whole liver decellularization by two different methods. To present the results of grafting rat and sheep decellularized liver matrix (DLM) into the normal rat liver and compare natural cell seeding process in homo/xenograft of DLM. To compare the results of in vitro whole liver recellularization with rats' neonatal green fluorescent protein (GFP)-positive hepatic cells with outcomes of in vivo recellularization process.
