Accell® Advanced Bone Grafting Product

Accell contains natural bone morphogenetic proteins (BMPs) and growth factors with demineralized bone matrix (DBM) to accelerate the body’s natural healing response.

Natural Healing

Accell features a concentrated form of the same BMPs and growth factors that the human body produces to form new bone—with nearly five times more BMPs than DBM alone.1 Because Accell contains only human bone and Reverse Phase Medium, a proprietary carrier, it eliminates the potential for reaction to non-human collagen.

Easy Handling

Our proprietary Reverse Phase Medium makes Accell moldable and easy to pack into any shape defect. It requires no special handling, storage, thawing, mixing or setting. Accell thickens at body temperature to hold the graft in place and resists irrigation to allow for better graft containment.

Proven Results

Accell contains BMPs and growth factors with DBM to accelerate the body’s healing response. In nature, these elements work together as part of the natural bone formation process2:

  • Growth factors (TGF-ß and IGF-1) recruit stem cells to the surgical site. TGF-ß also stimulates the stem cells to replicate, creating the cellular foundation for new bone.
  • VEG-F stimulates the formation of new blood vessels, increasing blood flow to the site. BMP-2, BMP-4 and BMP-7 transform stem cells into osteoblasts (bone forming cells).
  • FGF and PDGF promote replication of stem cells and osteoblasts. As the osteoblasts form, they organize themselves to create new bone.

Bone Healing Study3 Results:

Accell vs. First Generation DBM after 4 weeks

Images depict skeletally mature sheep model. Cylindrical 5mm metatarsal defect created in tibial diaphysis.

Control

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 DBM particles. The inert carrier has been metabolized. (DynaGraft II®).

Accell

More bone formation is evident immediately adjacent to the bone repair surfaces and within the interior of the defect. Accell delivers naturally-occurring BMPs and Growth Factors.

E-Beam Sterilization

Every lot of Accell is sterilized using a low-dose electron beam, a process that has been shown to preserve the osteoinductive power of BMPs.4
