A ghost heart?

Yesterday we discussed the idea of 3D-printed organs. Though that technology is developing fast, it’s still far from any practical applications. Another solution for the shortage of organs, would be xenotransplantation. However that approach has it’s own differences, namely the risk of (hyperacute) rejection. Genetically engineered pigs have been studied as a solution of this problem, but this only counters hyperacute rejection. A third option is to combine xenotransplantation with tissue engineering. In this process a pig organs is decellurized so that only the structure of that organ is left. Subsequently tissue from a patient are placed on this structure, and with as final result an organ which will not rejected by the recipient’s body.
