abstract = {Whole-organ engineering is an innovative field of
regenerative medicine with growing translational
perspectives. Recent reports suggest the feasibility of
decellularization and repopulation of entire human size
hearts. However, little is known about the susceptibility of
epicardial adipose tissue (EAT) to decellularization. In
this study, human size hearts of ovine donors were subjected
to perfusion-based decellularization using detergent
solutions. Upon basic histological evaluation and total DNA
measurement myocardial regions prove largely decellularized
while EAT demonstrated cellular remnants, further confirmed
by transmission electron microscopy. Western blot analysis
showed a significant reduction in lipid-associated and
cardiac proteins. However, gas chromatography revealed
unchanged proportional composition of fatty acids in EAT of
decellularized whole hearts. Finally, cell culture medium
conditioned with EAT from decellularized whole hearts had a
significant deleterious effect on cardiac fibroblasts. These
data suggest that perfusion decellularization of human size
whole hearts provides inconsistent efficacy regarding donor
material removal from myocardial regions as opposed to EAT.},
