ABCB5⁺ mesenchymal stem cells enable high-ratio cellular augmentation of bone grafts without loss of osteogenic function
Autologous bone grafting remains the standard for reconstruction of bone defects but is constrained by limited graft volume and loss of osteogenic capacity when expanded with acellular materials. We hypothesized that allogeneic ABCB5⁺ mesenchymal stem cells (MSCs) can serve as a biologic cell source to augment bone mar...
