* Development of a morphogenetically active scaffold for three-dimensional growth of bone cells: biosilica-alginate hydrogel for SaOS-2 cell cultivation.

- Polymeric silica is formed from ortho-silicate during a sol-gel formation process, while biosilica is the product of an enzymatically driven bio-polycondensation reaction. Both polymers have recently been described as a template that induces an increased expression of the genes encoding bone morphogenetic protein 2 (BMP-2) and osteoprotegerin in osteoblast-related SaOS-2 cells; simultaneously or subsequently the cells respond with enhanced hydroxyapatite formation. In order to assess whether the biocompatible polymeric silica/biosilica can serve as a morphogenetically active matrix suitable for three-dimensional (3D) cell growth, or even for 3D cell bioprinting, SaOS-2 cells were embedded into a Na-alginate-based hydrogel. Four different gelatinous hydrogel matrices were used for suspending SaOS-2 cells: (a) the hydrogel alone; (b) the hydrogel with 400 μM ortho-silicate; (c) the hydrogel supplemented with 400 μM ortho-silicate and recombinant silicatein to allow biosilica synthesis to occur; and (d) the hydrogel with ortho-silicate and BSA. The SaOS-2 cells showed an increased growth if silica/biosilica components were present in the hydrogel. Likewise intensified was the formation of hydroxyapatite nodules in the silica-containing hydrogels. After an incubation period of 2 weeks, cells present in silica-containing hydrogels showed a significantly higher expression of the genes encoding the cytokine BMP-2, the major fibrillar structural protein collagen 1 and likewise of carbonic anhydrase. It is concluded that silica, and to a larger extent biosilica, retains its morphogenetic/osteogenic potential after addition to Na-alginate-based hydrogels. This property might qualify silica hydrogels to be also used as a matrix for 3D cell printing.
