US Patent 11890396 Bone graft and methods of fabrication and use

Provided herein is a living bone graft including a biofabricated graft core including demineralized bone matrix and a carrier and a pre-vascularized shell at least partially enrobing the graft core, the pre-vascularized shell including isolated, intact adipose-derived microvessel fragments, mesenchymal stem cells, and collagen. The disclosed bone grafts include stromal cells that differentiate and microvessels that inosculate to provide a functional microvasculature, thereby approximating native bone repair as the graft matures in the patient. Also provided herein are methods of fabricating a bespoke, living, vascularized bone graft and methods of treating a segmental bone defect in a patient.
