Porous polycaprolactone (PCL) scaffolds were fabricated by using the CO2gas foaming/salt leaching process and then PCL scaffolds surface was treated by oxygen or nitrogen gas plasma in order to enhance the cell adhesion, spreading, and proliferation. The PCL and NaCl were mixed in the ratios of 3 : 1. The supercritical CO2gas foaming process was carried out by solubilizing CO2within samples at 50°C and 8 MPa for 6 hr and depressurization rate was 0.4 MPa/s. The oxygen or nitrogen plasma treated porous PCL scaffolds were prepared at discharge power 100 W and 10 mTorr for 60 s. The mean pore size of porous PCL scaffolds showed 427.89 μm. The gas plasma treated porous PCL scaffolds surface showed hydrophilic property and the enhanced adhesion and proliferation of MC3T3-E1 cells comparing to untreated porous PCL scaffolds. The PCL scaffolds produced from the gas foaming/salt leaching and plasma surface treatment are suitable for potential applications in bone tissue engineering.

This work aimed to develop novel composite biomaterials for bone tissue engineering (BTE) made of bioactive glass nanoparticles (Nbg) and alginate cross-linked with Cu 2+ or Ca 2+ (AlgNbgCu, AlgNbgCa, respectively). Two-dimensional scaffolds were prepared and the nanocomposite biomaterials were characterized in terms of morphology, mechanical strength, bioactivity, biodegradability, swelling capacity, release profile of the cross-linking cations and angiogenic properties. It was found that both Cu 2+ and Ca 2+ are released in a controlled and sustained manner with no burst release observed. Finally, in vitro results indicated that the bioactive ions released from both nanocomposite biomaterials were able to stimulate the differentiation of rat bone marrow-derived mesenchymal stem cells towards the osteogenic lineage. In addition, the typical endothelial cell property of forming tubes in Matrigel was observed for human umbilical vein endothelial cells when in contact with the novel biomaterials, particularly AlgNbgCu, which indicates their angiogenic properties. Hence, novel nanocomposite biomaterials made of Nbg and alginate cross-linked with Cu 2+ or Ca 2+ were developed with potential applications for preparation of multifunctional scaffolds for BTE.

Bone diseases and injuries have a major impact on the quality of life. Classical treatments for bone repair/regeneration/replacement have various disadvantages. Bone tissue engineering (BTE) received a great attention in the last years. Natural polymers are intensively studied in this field due to their properties (biocompatibility, biodegradability, abundance in nature, high processability). Unfortunately, their mechanical properties are poor, which is why synthetic polymers or ceramics are added in order to provide the optimal compressive, elastic or fatigue strength. Moreover, growth factors, vitamins, or antimicrobial substances are also added to enhance the cell behavior (attachment, proliferation, and differentiation). In this review, new scientific results regarding potential applications of chitosan-, alginate-, and gelatin based biocomposites in BTE will be provided, along with their in vitro and/or in vivo tests.

Chitosan-based material has been widely used as bone substitute due to its good biocompatibility and biodegradability. However, the hydrophobic surface of chitosan film constrains the osteogenesis mineralization in the process of bone regeneration. For this reason, we develop a novel polydopamine-modified chitosan film suitable for bone tissue engineering applications by a simple and feasible route in this study. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirm the process of surface modification. For comparison, surface wettability, the capacity of mineralization in vitro, and biocompatibility of the chitosan film and the polydopamine-modified chitosan film were assessed. Research results indicate that the polydopamine-modified chitosan film has good hydrophilicity. It is very evident that the polydopamine treatment significantly influences the biomineralization capacity of the chitosan-based substrates, which enhance the growth rate of apatite on the modified chitosan film. Besides, MC3T3-E1 osteoblast experiments demonstrate that the cells can adhere and grow well on the polydopamine-modified chitosan film. It is anticipated that this polydopamine-modified chitosan film, which can be prepared in large quantities simply, should have potential applications in bone tissue engineering.

Nanodiamond (ND) is an attractive nanomaterial for reinforcement of biopolymers due to the ND’s superior mechanical and chemical properties, and low biotoxicity. A novel composite material has been produced for bone scaffolds utilizing the biodegradable polymer poly(L-lactic acid) (PLLA) and octadecylamine-functionalized nanodiamond (ND-ODA). Composites were prepared by admixing to a PLLA/chloroform solution chloroform suspension of ND-ODA in concentration range of 0–10% (w/w). The dispersion of ND-ODA evaluated by transmission electron microscopy (TEM) shows uniform distribution of ND-ODA in PLLA matrix. The composites were characterized by differential scanning calorimetry (DSC). DSC analysis of the composites showed no significant thermal behavior changes with the addition of ND-ODA into the polymer. Biomineralization test shows that ND-ODA can enhance the mineral deposition on scaffolds. Improved mechanical properties and good biocompatibility with enhanced biomineralization combined suggest that ND-ODA/PLLA might have potential applications for bone tissue engineering.
