The rising incidence of bone disorders has resulted in the need for minimally invasive therapies to meet this demand. Injectable bioactive filler, alone or with cells, could be applied in a minimally invasive manner to fulfill irregular cavities in non-load bearing sites, which do not require high mechanical properties. Thermosensitive chitosan hydrogels that transition from a liquid to a mechanically stable solid at body temperature provide interesting features as in-situ injectable cytocompatible biomaterials, but they are not osteoconductive. Osteoconductivity can be applied in combination with bioactive ceramics e.g., 45S5-Bioglass® (BG). However, BG addition in chitosan hydrogels results in pH elevation, due to rapid ions release, which adversely affects gel formation, mechanical properties, and cytocompatibility. To address this, we created hybrid hydrogels, where BG is concentrated in chitosan-based microbeads, incorporated in in-situ gelling chitosan hydrogels. We then compared the hybrid hydrogels' properties to chitosan hydrogels with homogenously distributed BG. By varying the stirred emulsification process, BG percentage, and CH formulation, we could tune the microbeads' properties. Incorporation of BG microbeads drastically improved the hydrogel's compressive modulus in comparison to homogeneously distributed BG. It also strongly increased the survival and metabolic activities of encapsulated cells. Calcium/phosphate increase on BG microbeads suggests hydroxyapatite formation. The small diameter of microbeads allows minimally invasive injection through small needles. The feasibility of freezing and thawing microbeads provides the possibility of long-term storage for potential clinical applications. These data indicate that this hybrid hydrogel forms a promising injectable cell-laden bioactive biomaterial for the treatment of unloaded bone defects.
