In-Lab Manufacturing of Decellularized Rat Renal Scaffold for Kidney Bioengineering.

Whole-organ decellularization is recently gaining interest in the transplantation field as strategy to obtain acellular scaffold only composed by extracellular matrix. These structures, that still remain organ-specific in terms of biological cues and tridimensional morphology could be then recellularized with patient's autologous cells. The final result should be a nwe transplantable autologous organ that should by-pass, at the same time, the problem of organ shortage and secondly the consequences related to the immunosuppression need. Herein we describe the protocol to manufacture a whole-organ transplantable rat kidney scaffold by a dual-detergent (Triton X-100 and SDS) arterial peristaltic perfusion. Final results show whole-renal acellular scaffold with contextual preservation of tridimensional architecture and biological properties deriving from the extracellular matrix composition.
