چکیده

Perfusion decellularization of cadaveric hearts removes cells and generates a cell-free extracellular matrix scaffold containing acellular vascular conduits, which are theoretically sufficient to perfuse and support tissue-engineered heart constructs. This article contains additional data of our experience decellularizing and testing structural integrity and composition of a large series of human hearts, "Acellular human heart matrix: a critical step toward whole heat grafts" (Sanchez et al., 2015) [1]. Here we provide the information about the heart decellularization technique, the valve competence evaluation of the decellularized scaffolds, the integrity evaluation of epicardial and myocardial coronary circulation, the pressure volume measurements, the primers used to assess cardiac muscle gene expression and, the characteristics of donors, donor hearts, scaffolds and perfusion decellularization process.

Construction of autologous human heart valves based on an acellular allograft matrix.

OBJECTIVE Tissue engineered heart valves based on polymeric or xenogeneic matrices have several disadvantages, such as instability of biodegradable polymeric scaffolds, unknown transfer of animal related infectious diseases, and xenogeneic rejection patterns. To overcome these limitations we developed tissue engineered heart valves based on human matrices reseeded with autologous cells. METHO...

RGD-modified acellular bovine pericardium as a bioprosthetic scaffold for tissue engineering.

Acellular biological tissues, including bovine pericardia (BP), have been proposed as natural biomaterials for tissue engineering. However, small pore size, low porosity and lack of extra cellular matrix (ECM) after native cell extraction directly restrict the seed cell adhesion, migration and proliferation and which is a vital problem for ABP's application in the tissue engineered heart valve ...
