In vitro
Cultures of osteoblasts, osteoclasts, synoviocytes and chondrocytes (bi- and tri-dimensional models) to mimic the disease and assess drug functionality by measuring:
- Cytokine Release
- Collagen Synthesis
- Hyaluronic Acid Synthesis
- GAG Synthesis
- Enzyme Activities
- Bone Mineralization
- Bone Resorption/Formation
- Phenotype
- Gene Expression (PCR, Qpcr, Microarrays)
- Proteome Analysis
Models to study drug stability/solubility in synovial fluid (simulated or fresh, from healthy and osteoarthritic donors.
In vivo
- Osteoporosis (by ovariectomy, immobilization, glucocorticoidinduced)
- Osteoarthritis (by ACL resection, the test substance can also be administered IA)
- Rheumatoid Arthritis (induced by collagen injection)
- Osteointegration of titanium implants
- Fracture healing
Observations
- Histology
- Histomorphometry
- Immunohistochemistry
- Blood and urine analyses for the detection of specific markers
- Gene Expression
- Proteomic Analysis
