The Accell Process
Each donor lot of DBM is divided in two. Half is reserved for the final formulation.
The remaining half undergoes the Accell process which results in flowable carrier with osteoinductive potential.
The flowable carrier is then combined with the DBM particles consisting of two components with osteoinductive potential.
IsoTis OrthoBiologics terminally sterilizes every lot of Accell product with a low-dose electron beam, a process that has been demonstrated to preserve the osteoinductive potential of bone growth factors.
The Accell Advantage
Skeletally mature sheep model.
Cylindrical 5 mm metatarsal defect created in tibial diaphysis.
Results after 4 weeks
Control - Empty
Minimal bone regeneration observed at 4 weeks. Healing limited to area adjacent to host bone.
1st Generation DBM
Bone regeneration occurs throughout the defect, caused by the presence of osteoinductive DBM particles. The inert carrier has been metabolized.
Significantly more bone formation is evident immediately adjacent to the bone repair surfaces and within the interior of the defect. We believe this occurs because of the immediate access to the BMPs in the Accell products.
Accell Bone Matrix's increased surface area provides access to natural bone proteins.
Natural bone protein content of ABM and particulate DBM was measured in vitro over time using an Enzyme Linked Immunosorbent Assay (ELISA). The results are shown graphically and indicate that bone protein was detectable in a saline solution containing ABM at earlier time points compared to that of particulate DBM.
The higher surface area and more open pore structure of ABM provides accessibility to the bone protein, without the need to be broken down. This analysis shows that while ABM provided early accessibility of natural bone protein, particulate DBM provides for accessibility of natural bone protein at later time points.
