AB  - Dental pulp stem cells (DPSCs) are mesenchymal stem cells that may have a versatile and abundant application in regenerative medicine and dentistry due to their availability, possibility of isolation from different types of teeth and potential to differentiate into several cell types. In recent years, there is an emerging trend of the use of nanomaterials in medicine and dentistry that, by virtue of their unique properties, have become very attractive as a tool for the treatment of bone tissue defects. The aim of our study was to examine the potential of synthesized nanomaterial, intended for bone tissue engineering and regenerative applications, biphasic calcium phosphate coated with poly-D,L-lactide-co-glycolide (CP/PLGA), to influence the osteogenic differentiation of DPSCs. Cells were obtained from the mature healthy teeth by outgrowth of the cells from undigested pulp pieces during culturing, in standard cell culture conditions. Cells were subjected to osteogenic differentiation for seven and 14 days by culturing the cells with two concentrations of CP/PLGA nanoparticles in the presence or absence of osteogenic supplements in the media. Osteogenic differentiation was assessed by phase contrast microscopy as well as by Von Kossa and Alizarin Red S staining of formed inorganic deposits. The results showed that CP/PLGA influenced osteogenesis in concentration-dependent manner and differently in osteogenic and standard cell culture media. The use of calcium phosphate-based nanomaterials in combination with DPSCs, under certain conditions, could be a promising approach in regenerative medicine and dentistry.

AB  - Nanomaterials represent a relatively new and developing class of materials that are widely used because of their unique mechanical and physiochemical properties. Due to the particles’ size and the ability to easily enter the cells and interact with different cellular components, nanoparticles can exhibit toxic effects in biological systems, so it is necessary to conduct a thorough in vitro biocompatibility testing. Our aim was to examine the in vitro genotoxic and apoptotic potential of two different synthesized nanomaterials intended for bone tissue engineering and regenerative applications: biphasic calcium phosphate coated with poly- D,L-lactide-co-glycolide (CP/PLGA) and cobalt-substituted hydroxyapatite (CoHAp), by DNA fragmentation assay. NB4 cells (acute promyelocytic leukemia cell line) were incubated with different concentrations of CP/PLGA and CoHAp nanomaterials for 24 hours. Cells cultured in standard medium, without nanomaterials, were used as negative control and cells treated with hydrogen peroxide were used as positive control. After incubation with materials the genomic DNA was extracted from the cells and applied on horizontal agarose gel electrophoresis. The results of DNA fragmentation assay were observed on gel documentation system. Higher examined concentrations of CP/PLGA caused DNA fragmentation at some extent with DNA laddering at approximately 180 bp which is characteristic for later stages of apoptosis, while DNA laddering was not seen in the case of CoHAp at the same concentrations. Although both materials are in the form of nanoparticles, a different effect in apoptotic DNA fragmentation was observed which suggests that the chemical composition of nanomaterials notably affects the genotoxicity and apoptosis potential in addition to the particle size.

AB  - Nanomaterials are nowadays widely used in various fields of biomedicine. Before the application of biomaterials they have to be tested and fulfill some criteria. The first tests that should be performed after synthesis of some new nanomaterial with potential application in biomedical fields are biocompatibility tests. The aim of this study was to examine the influence of nanomaterial calcium phosphate/poly-(dl-lactide-co-glycolide) (CP/PLGA) on proliferation and adherence of HeLa cells in culture. For both proliferation and adherence examination, cells were treated with suspension of nanomaterial CP/PLGA at concentrations 5, 50 and 500 µg/mL, made in cell culture medium. There were four different types of treatment: (1) cells incubated with CP/PLGA for 3 days; (2) cells incubated with CP/PLGA for 6 days; (3) cells incubated first with CP/PLGA for 3 days and then for the next 3 days with medium and (4) cells incubated first with medium for 3 days and then for the next 3 days with CP/PLGA. Three days after incubation of HeLa cells with different concentrations of CP/PLGA nanoparticles’ suspension, the concentration of 5 µg/mL had mild inhibitory effect on proliferation. Increasing CP/PLGA concentration, there was stimulatory effect on cells’ proliferation. With prolonged incubation period, this dose dependence is lost. The highest adherence of HeLa cells was observed when cells were incubated with the highest examined concentration of CP/PLGA suspension, in both 3-day and 6-day incubation period. Based on the results obtained in our study, we can conclude that the effect of the suspension of nanomaterial CP/PLGA on proliferation and adherence of HeLa cells depends on the duration of incubation with the cells as well as the material concentration and type of the treatment.

In recent years, biomaterials attracted great attention primarily because of the wide range of biomedical applications. This paper focuses on the practical aspects of instrumental methods and techniques that were most often applied (X-ray methods, vibrational spectroscopy (IR and Raman), magnetic-resonance spectroscopy (NMR and ESR), mass spectrometry (MS), atomic absorption spectrometry (AAS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES), thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC), scanning electron microscopy (SEM), transmission electron microscopy (TEM)) in the structural investigation and physicochemical characterization of biomaterials and bone tissue. The application of some other physicochemical methods was also discussed. Hands-on information is provided about these valuable research tools, emphasizing practical aspects such as typical measurement conditions, their limitations and advantages, interpretation of results and practical applications.

AB  - The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500–1300 cm−1.

AB  - We have examined the effect of extracts of the calcium phosphate/poly(DL-lactide-co-glycolide) (CP/PLGA) and cobalt-exchanged hydroxyapatite (CoHAp), on the viability of Saos2 osteoblastlike cells. Extracts were prepared by incubation for 3 days at 37°C in the cultivation medium. Conductivity and pH value of extracts were measured before viability assay. Cell viability was estimated by MTT test performed after 24 h incubation of cells with various concentrations of extracts. Extract of CP/PLGA acted more cytotoxic on osteoblasts than the extract of CoHAp. This difference in the effect of examined extracts can be explained by their different pH value and conductivity.

AB  - The aim of this study was to examine the effects of nanoparticles of calcium phosphate/poly-(DL-lactide-co-glycolide) (NPs-CP/PLGA) on viability and growth of different cell lines in vitro. HeLa and MDCK cells were incubated with different concentrations of suspension and extract of NPs-CP/PLGA. Concentrations of suspension were in the range from 1.6 μg/ml to 5000 μg/ml and extract in the range from 2.5% to 50%. After incubation, MTT test was performed. Our results indicate that examined nanomaterial shows different effects depending on type of the cells, applied concentration of nanomaterial as well as whether it is examined suspension or extract.
