| Program: | SRDA |
| Project leader: | Ing. Medvecký Ľubomír, DrSc. |
| Annotation: | Tissue engineering is a combination of cells, biochemical, physico-chemical factors and biomaterials to improve orreplace of biological functions. Many definitions of tissue engineering cover applications, in practice the term isclosely associated with applications that repair or replace portions of or whole tissues (cartilage, bone, bloodvessels, skin, muscle, nerve, etc.). Often, the tissues involved require certain mechanical and structural propertiesfor proper functioning which biomaterials have to guarantee. For the testing of biomaterial, the various methods areused in relation to their biocompatibility with individual organisms. Chicken embryo /or quail embryo is aninteresting, recognized a very suitable animal model for studying angiogenesis by ex ovo or in ovo method. This isa low-tech method, which makes it possible to continuously monitor angiogenesis, to easily and quickly obtainresults, and to evaluate them in a short time. The project of basic research is focused on the study of angiogenesisof biopolymer composites based on polysaccharides with or/without the hydrogel component implanted on thechick or/quail chorioallantoic membrane using macroscopic, histological, immunohistochemical and molecularmethods. Modern and advanced scientific approach of developing new biomaterials used in the present project ischaracterized by tight multidisciplinary connection of biomaterial engineering methods and in vivo studied systems that with high probability allow assess their suitability as a models for testing biomaterials on angiogenesis. |

| Komponat – Kompozitné biomateriály s komplexnými prírodnými aditívami | |
| Composite biomaterials with complex natural additives | |
| Program: | SRDA |
| Project leader: | Ing. Medvecký Ľubomír, DrSc. |
| Annotation: | The project is focused on the research of modified and new types of composite biocements with complex natural additives, which will self-hardened as well as injectable according to the need for use and will be characterized by high bioactivity and biocompatibility with bone tissue. In principle, the preparation of composite biocement systems is applied in combination with complex natural additives without specific extraction of selected groups of compounds from natural products what preserves the simplicity of preparation, cheap final form of biomaterial as well as the "green principle" of their nature, composition and response. Composite biocements will be used inorthopedics (treatment of bone and osteochondral defects and fractures) as well as in the reconstruction of bone injuries in the facial part or as filling cements in dentistry. |

| Kompozitné systémy na báze bioelastomérov a bioaktívnych fáz | |
| Composite systems based on bioelastomers and bioactive phases | |
| Program: | VEGA |
| Project leader: | RNDr. Sopčák Tibor, PhD. |
| Annotation: | As the population continues to grow, so does the number of surgeries in various fields of medicine, including reconstructive surgery and regenerative medicine. This implies a need for a research of such biomaterials that will closely mimic the structure of the original tissue. The present project will aim to address the issues related to the currently used bone implants, i.e. low mechanical properties with the simultaneous maintenance of their biological properties. The production of composite systems based on bioelastomers and bioactive phases in the form of bioceramics or cements is expected to take advantage of both components with the outstanding bioactivity, self-setting and handling properties of cements along with excellent elastic properties, mechanical reinforcement and improved biodegradation offered by elastomers. A great emphasis will be given on the production of glycerol carboxylate polyesters and their effective incorporation into the bioactive matrix. |

| Kompozitné horčíkovo-vápenato fosforečné biocementy s prídavkom koloidného oxidu kremičitého | |
| Composite magnesium-calcium phosphate biocements with addition of colloidal silicon dioxide | |
| Program: | VEGA |
| Project leader: | Ing. Štulajterová Radoslava, PhD. |
| Annotation: | The project is focused on the research and development of composite calcium phosphate biocements containing magnesium and colloidal silica particles, which represents an improvement in particular, in the viscositycharacteristics of cement pastes. The intention is that the addition of colloidal SiO2 will contribute to a fastertransformation of calcium phosphate biocement to calcium deficient hydroxyapatite and change or improving the biocement characteristics, which are important in bone reconstruction. Resulting biocement system should haveenhanced mechanical strength that would be sustained over a longer time period during soaking in body fluids and should positively affect bioresorption with an active influence on specific cell lineages. |
