In vitro and in vivo evaluation of carbonate apatite-collagen scaffolds with some cytokines for bone tissue engineering
BACKGROUND Collagen is regarded as one of the most useful biomaterials. We tried to combine collagen and carbonate apatite (CA) with some cytokines in order to enhance bone formation ability. In this study, we found that CA-collagen sponge (CA-CS) was a possible candidate of newly graft material for bone formation. MATERIALS AND METHODS CA-CS was fabricated by the following procedure. One wt%...
متن کاملComparison of Purity and Properties of Hydroxyl Carbonate Apatite Extracted from Natural Thigh Bone by Different Physio-chemical Methods
New approaches to extracting natural hydroxyl carbonate apatite from bio waste of bovine bones cortical femur have been developed. To extract pure and natural bio ceramics, three different treatments have been applied: 1-Calcination heat treatment at temperature of 700 , 2-alkaline hydrothermal at temperature of 275 and 3-Pressurized low polarity water at temperature of 250 . Raw bovine bone an...
متن کاملFormation and in Vivo Evaluation of Carbonate Apatite and Carbonate Apatite/CaCO_{3} Composite Films Using the Thermal Substrate Method in Aqueous Solution
We have studied the formation and carried out an in vivo evaluation of carbonate apatite (CO3-Ap) and CO3-Ap/CaCO3 composite coatings on titanium substrates using the thermal substrate method. The coatings were formed on commercial pure titanium rods (diameter = 2mm, length = 5mm) and plates (thickness = 0.3mm) by the thermal substrate method in an aqueous solution that contained Ca(H2PO4)2, Ca...
متن کاملProperties of calcium carbonate-containing composite scaffolds.
Bone grafting in skeletal reconstruction has become a common task of orthopedic surgeon. Three-dimensional, porous, degradable scaffolds are often used to provide support while the new tissue can be formed in situ. There are numerous materials and techniques involved; however, each has certain drawbacks. One of the patented ceramic bone grafts is made of coral that has many benefits, e.g., its ...
متن کاملFabrication and Physical Evaluation of Gelatin-Coated Carbonate Apatite Foam
Carbonate apatite (CO₃Ap) foam has gained much attention in recent years because of its ability to rapidly replace bone. However, its mechanical strength is extremely low for clinical use. In this study, to understand the potential of gelatin-reinforced CO₃Ap foam for bone replacement, CO₃Ap foam was reinforced with gelatin and the resulting physical characteristics were evaluated. The mechanic...
