This study aimed to evaluate the effectiveness of a novel calcitonin-loaded calcium phosphate composite bone cement in vitro and in vivo. The novel composite bone cements were composed of NuROs injectable bone graft substitute, type I collagen, and/or salmon calcitonin. The setting time, porosity, wettability, compressive strength, compressive modulus, and crystallographic structures of cement specimens were determined. Degradation rate, calcitonin release rate, and osteoinductivity were assessed in vitro. In addition, osteogenic effect was examined in a rabbit model of femoral defect. The results revealed that addition of collagen/calcitonin did not substantially alter physical properties and degradation rate of bone cement specimens. Calcitonin was released into culture medium in a two-phase manner. Osteogenic effect of conditioned medium derived from calcitonin containing bone cement was observed. Finally, de novo bone growth and bone mineralization across the bone defect area were observed in rabbits after implantation of composite bone cement specimens. In conclusion, this novel calcitonin-loaded composite calcium phosphate bone cement exhibits biocompatibility, bioresorbability, osteoinductivity, and osteoconductivity, which may be suitable for clinical use.

Introduction: A novel injectable calcium phosphate bone cement (osteopaste) has been developed. Its potential application in orthopaedics as a filler of bone defects has been studied. The biomaterial was composed of tetra-calcium phosphate (TTCP) and tricalcium phosphate (TCP) powder. The aim of the present study was to evaluate the healing process of osteopaste in rabbit tibia. Materials and method: The implantation procedure was carried out on thirty-nine of New Zealand white rabbits. The in vivo bone formation was investigated by either implanting the Osteopaste, Jectos or MIIG – X3 into a critical size defect (CSD) model in the proximal tibial metaphysis. CSD without treatment served as negative control. After 1 day, 6 and 12 weeks, the rabbits were euthanized, the bone were harvested and subjected for analysis. Results: Radiological images and histological sections revealed integration of implants with bone tissue with no signs of graft rejection. There was direct contact between osteopaste material and host bone. The new bone was seen bridging the defect. Conclusion: The result showed that Osteopaste could be a new promising biomaterial for bone repair and has a potential in bone tissue engineering.

Dsc Analyses

Crab shells are waste product, rich with calcium compound. Calcium element is often used as a material for bone scaffold due to its bioactive and biodegradation properties. In this study, calcium phosphate (CaP) nanoparticles were synthesized from crab shells through a wet chemical route. The CaP nanoparticles were then sintered and mixed with poly(lactic-co-glycolic acid) (PLGA) to form a bone cement composite. The mixture was casted in a cylinder shape and it was characterized through ATR-FTIR, XRD, FESEM, contact angle and DSC analyses. The CaP pellet and the CaP/PLGA bone cement composite were then subjected to in vitro simulated body fluid (SBF) bioactivity test. The CaP/PLGA bone cement composite was found to have a composition of crystal CaP and PLGA with a tolerable glass transition state, suitable to be used in a physiological environment. The CaP nanoparticles were agglomerated on the 3D interconnected surface of PLGA. The hydrophobicity of the CaP was increased (66.94%) with the addition of PLGA as a binder matrix where this composite has induced the formation of apatite layer. This bioactive property is crucial in fabricating a bone substitute material as it can promotes cell penetration, attachment and proliferation..

In Vitro Response

We recently developed a new biomimetic calcium phosphate bone cement enriched with gelatin (GEL-CP) which exhibits improved mechanical properties with respect to the control cement (C-CP) and a good response to osteoblast-like cells. In this work, we have extended the investigation to primary culture of osteoblasts derived from normal (N-OB) and osteopenic (O-OB) sheep bones cultured on samples of GEL-CP, and their behavior was compared to that of cells cultured on C-CP as control. Cell morphology, proliferation, and differentiation were evaluated at 3 and 7 days. Preliminary in vivo tests were carried out onto critical size defects in the radius diaphysis of rats.

Preliminary Study

N,O-carboxymethyl chitosan (CMCTS) was added in Calcium phosphate bone cement (CPC). A preliminary study was carried out in order to evaluate the biocompatibility of CPC containing CMCTS. In vitro tests were done using extract liquid from normal saline. The result showed that the biological reaction complied with standards of GB/16886 and the composite might have good biocompatibility.
