    From Chemistry to Clinic: Polysaccharide-Bioceramic Composites for Tissue Engineering Applications
    (Mary Ann Liebert, Inc, 2025) Yakubogullari, Nilgun; Yilmaz-Dagdeviren, Hilal Deniz; Arslan-Yildiz, Ahu
    Composite scaffolds combining polysaccharides and bioceramics represent next-generation scaffolds extensively investigated in tissue engineering (TE) and biomedical applications. Polysaccharides such as chitosan, hyaluronic acid, and pectin mimic the extracellular matrix components with their tunable physicochemical properties, enabling a favorable microenvironment for cell adhesion, proliferation, and cell-matrix interactions. On the other hand, bioceramics, including calcium phosphate, hydroxyapatite, and bioactive glasses, enhance the mechanical properties of the material and offer structural integrity and osteoconductive properties. While they have generally been preferred to be used in bone TE and dental applications, various studies have also demonstrated their potential in cartilage regeneration, wound healing, and broader biomedical applications. Recent advancements in material design and scaffold fabrication techniques, particularly 3D printing and electrospinning, have provided precise engineering of materials and fabrication of scaffolds for desirable mechanical properties and biological performance. These innovations foster the development of patient-specific scaffolds, thereby paving the way for applications in personalized medicine. This review critically summarizes alternative polysaccharides, bioceramics, and composite materials used in TE and biomedical applications. It also highlights advanced fabrication strategies and finally explores the translational potential of these biocomposites. By integrating emerging technologies, this review aims to provide alternative and sustainable materials for the development of next-generation scaffolds that meet clinical needs.Impact Statement This study introduces polysaccharide-bioceramic composites with enhanced mechanical and biological properties for tissue engineering. Beyond bone and dental repair, their applications increasingly extend to wound healing, cartilage, cardiac, and muscle regeneration with drug delivery, angiogenesis, and neurogenesis. By mimicking the native extracellular matrix, these composites support cell growth and tissue regeneration, offering a versatile platform for advanced regenerative therapies.

    Proliferative Effects and Cellular Uptake of Ceramic Nanoparticles in Cancer and Normal Cells
    (Univ Chemistry & Technology, Prague, 2024) Cesmeli, Selin; Tomak, Aysel; Winkler, David A.; Karakus, Ceyda Oksel
    The high biocompatibility, wear resistance, and high surface area-to-volume ratios of calcium phosphate (CaP) nanoparticles make them materials of great interest for a very broad range of medical applications, such as dentistry, drug delivery, biomedical imaging, gene transfection and silencing, biomedical imaging, immunisation, and bone substitution. While their use as an enamel remineralisation agent, a bone substitution material, an implant coating, and drug/gene delivery agents is widely approved by the regulating bodies, insufficient attention has been paid to the interactions of CaP-based nanoparticles with cells and organs once in the bloodstream and distributed through the body. Here, three different CaP-based nanoparticles (CP: calcium phosphate, TCP: tricalcium phosphate, and HAp: hydroxyapatite) were examined for the proliferative effects, oxidative damage potential, and cellular uptake in the human embryonic kidney (HEK293) and pancreatic cancer (Panc-1) cell lines. The physicochemical properties of the nanoparticles were characterised by Teller analysis, and X-ray diffraction spectroscopy. Maximum proliferative effects were generated by 400 mu g center dot ml-1 TCP (220 %) in HEK293 cells. Interestingly, although CP nanoparticles had the highest reactive oxygen species formation capacity in the HEK293 cells, they exhibited the lowest proliferative effects and a relatively low internalisation rate, suggesting a minimal correlation between the cellular uptake level and oxidative potential.
