Porous granular composite biomaterials based on sodium alginate and calcium phosphate component: 1% sodium alginate; sodium alginate with gelatin (80/20); calcium phosphate ceramics (CHA, TCP and OCP) and composite materials alginate/CHA, alginate/TCP, alginate/OCP, alginate/gelatin (80/20)/TCP and alginate/TCP/CHA/OCP were investigated for cytotoxicity and matrix (for cells) properties in dynamics of cultivation (up to 21 days). Two adhesive cell lines - immortalized human fibroblasts (HF, strain 1608 hTERT) and human osteosarcoma (MG-63) were used for in vitro MTT assay. OCP material showed its cytotoxicity while all its composites possessed weak matrix properties. For further research on the development of prototyping technologies 3 samples of composite materials were selected: alginate/CHA, alginate/TCP and alginate/gelatin (80/20)/TCP that are characterized by cytocompatibity and the presence of either expressed or moderate matrix properties of the surface for cells.
