In an effort to set living pericardial material for aortic valve reconstruction, we have previously assessed the efficiency of a recellularization strategy based on a perfusion system enabling mass transport and homogenous distribution of aortic valve-derived ‘interstitial’ cells inside decellularized pericardial material. In the present report, we show that oscillating perfusion favours deposition of valve proteins in the decellularized pericardium determining a partial tissue maturation. Investigation of cell dynamics inside the recellularized tissue constructs showed proliferation of valve cells inside the pericardial material and activity of a proliferation-supporting pathway, likely controlled by the YAP transcription factor, a crucial component of the Hippo-dependent signalling cascade. These results represent a step forward in the definition of a strategy to produce a fully engineered tissue for replacing the failing aortic valves.
