Vascular Grafts Derived from Decellularized Tissues Modified with 3D Bioprinting
Original language description
Cardiovascular surgery lacks suitable biomaterials for bypass surgery and patch repair. Currently available grafts for bypass surgery possess many shortcomings. In this study we are aiming to prepare vascular grafts and patches based on decellularized and lyophilized matrices (pericardium and vessels) with further recolonization with adipose derived stromal or Wharton’s jelly stromal cells. Decellularization was held in custom build automated system allowing cyclic change of decellularization agents and cleaning water maintaining reproducible process. To ensure homogenous recolonization of prepared substrates the 3D bioprinting and microextrusion method was utilized. Planar tissues were recolonized using 3D bioprinting method. Porcine collagen with incorporated cells was used. Then to coat inner lumen of tubular tissue microextrusion method was created. It uses special microcanulas where collagen with cells was extruded, leaving inner lumen homogenously coated. Prepared planar patches and tubular graft were then implanted into pigs for one month observation.
