This study focused on the degradation properties of gelatin microparticles incorporated in calcium phosphate (CaP) cement and the subsequent effect of these composites on bone formation. Positively charged alkaline gelatin (type A) microparticles or negatively charged acidic gelatin (type B) microparticles were incorporated in CaP cement, which was implanted in critical-sized cranial defect in ...
Aim: to investigate and describe, through a systematic review, the biological behavior osteogenic potential of composite biomaterials containing hydroxyapatite (HA), alginate gelatin, in different associations, after vivo implantation. Materials Methods: for search selection articles, Medical Literature Analysis Retrieval System Online (PubMed/MEDLINE) Scientific Electronic Library (SciELO) dat...
The generation of induced-pluripotential stem cells- (iPSCs-) derived mesenchymal stem cells (iMSCs) is an attractive and promising approach for preparing large, uniform batches of applicable MSCs that can serve as an alternative cell source of primary MSCs. Appropriate culture surfaces may influence their growth and differentiation potentials during iMSC derivation. The present study compared ...
Fabricating ideal scaffolds for bone tissue engineering is a great challenge to researchers. To better mimic the mineral component and the microstructure of natural bone, several kinds of materials were adopted in our study, namely gelatin, polycaprolactone (PCL), nanohydroxyapatite (nHA), and bone powder. Three types of scaffolds were fabricated using electrospinning; gelatin/PCL, gelatin/PCL/...
background and aims. autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. the complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (hbmg). the present study was conducted to compare the efficacy of hbmg and autograft on the reconstruction of bone defects in rats. materials and methods. in ...
Many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. This study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (E-BMG) in rabbit. E-BMG was prepared from tibia and femur of 4 Deutsche-Poland rabbits with average ages of 4-6 months. The prepared E-BMG was implanted in right incisor teeth pulps of...
Malnutrition, particularly protein undernutrition, contributes to the occurrence of osteoporotic fracture by lowering bone mass. In this study, the effects of dietary protein on bone mineral density and body weight in protein undernutrition were compared between gelatin and milk casein. When mice were fed for 10 wk with a low protein diet containing 10(%) casein or 6% casein +4% gelatin, there ...
Fracture healing involves the coordinated actions of multiple cytokines. Bone morphogenetic protein 9 (BMP9) is an important factor in bone formation. The present study aimed to investigate the osteogenic potential of bone marrow stem cells (BMSCs) in response to adenoviral (Ad)BMP9, and the early fracture repair properties of AdBMP9 in surgically‑created fractures in osteoporotic rats. Alkalin...
Many bioactive molecules like recombinant human bone morphogenetic protein 2 (rhBMP-2) have been developed for mineralized bone grafts, for which proper scaffolds are necessary to successfully apply the bioactive molecules. In this study, we tested the osteogenic efficacy of rhBMP-2 produced in-house in combination with gelatin sponge as the scaffold carrier in a rabbit radial defect model. The...
