In addition, SURPASS indicated that the surface area of osteocytes was 0.36 ± 0.03 μm2 per 1 μm3 bone compartment and that the volume ratio of osteocyte cell body to bone compartment was 9.42% ± 1.18%.
NEURON TRACER showed that the length of osteocyte processes was 0.26 ± 0.02 μm per 1 μm3 bone compartment.
In early OA, the calcified cartilage layer is subjected to increased endochondral ossification (Suri & Walsh 2012), most likely triggered by vascular invasion from the subchondral bone compartment.
In the bone compartment, a more intense ALP staining was obtained following seeding with osteoblasts, confirming the μCT results which showed higher mineralization density for these scaffolds.
The implants were made of medical-grade PCL (mPCL) for the bone compartment whereas fibrin glue was used for the cartilage part.
This study describes the design of a biphasic scaffold composed of a Fused Deposition Modeling scaffold (bone compartment) and an electrospun membrane (periodontal compartment) for periodontal regeneration.
The patients and the families in this study were warned of the risk of developing adverse effects and complications such as deep infection, a severe inflammatory reaction, neuralgia, resorption of bone, compartment syndrome, heterotrophic ossification and local nerve compression.
In vitro data showed that the osteoblasts formed mineralized matrix in the bone compartment after 21 days in culture and that the PDL cell sheet harvesting did not induce significant cell death.
Further work can investigate the use of PET/CT to quantify the metabolic response of LAPC4-CR to novel agents and combination therapies using soft tissue and possibly bone compartment xenograft models.
In order to achieve simultaneous alveolar bone and periodontal ligament regeneration a cell-based strategy was carried out by combining osteoblast culture in the bone compartment and placement of multiple periodontal ligament (PDL) cell sheets on the electrospun membrane.
Femoral MAT was assessed by μCT (lipid binder osmium) using a semi-automated approach employing rigid co-alignment, regional bone masks and was normalized for total femoral volume (TV) of the bone compartment.
