Figure Lengend Snippet: (a) Cell proliferation of SaOS-2 cells onto the different CaP discs for 4 h, 7, 14 and 21 days. (b) ALP activity of SaOS-2 cells cultured onto the CaP substrates for 4 h, 7, 14 and 21 days. The same letter indicates no statistically significant differences for the same group at different time points while the same number denotes no statistically significant differences for each time point among all samples. (p < 0.05).

Article Snippet: SaOS-2 cell line (HTB-85), RAW 264.7 cell line (TIB-71), Pseudomonas aeruginosa (ATCC-27853) and Staphylococcus aureus (ATCC-25923) were purchased from American Type Culture Collection (VA, USA).

Figure Lengend Snippet: Merged CLSM images of SaOS-2 cells cultured for 4 h and 7 days on the nanostructured CaP substrates, as well as the Flat and Ti controls. Actin filaments were stained with Alexa Fluor™ 546 phalloidin (orange fluorescence signal) and nuclei with DAPI (blue fluorescence signal).

Figure Lengend Snippet: (a) mRNA expression of osteogenic genes ALPL, RUNX2 and SPP1 of SaOS-2 cells cultured directly onto the CaP substrates for 1, 3, 7 and 14 days, determined by real-time PCR (n = 3). (b) Interaction of RAW 246.7 cells with treated discs up to 7 days in cell culture. i) mRNA expression of pro-inflammatory genes TNF, IL1B and IL6 of cells in the direct cell culture, determined by real-time PCR for 1, 3 and 7 days (n = 3). All values are relativized to values of cells at day 1. ii) Protein expression level after 7 days of direct cell culture on the treated discs, measured by inflammation antibody array. Values of protein signal are quantified by image analysis and relativized to control. In Fig. a) and bi), the same letter indicates no statistically significant differences for the same group at different time points while the same number denotes no statistically significant differences for each time point among all samples. (p < 0.05).

Figure Lengend Snippet: Co-culture of P. aeruginosa and SaOS-2 cells on the nanostructured CaP discs, as well as Flat and Ti controls. a) Merged CLSM images of: i) a pre-implantation infection model, where the samples were first incubated for 6 h with P. aeruginosa and subsequently SaOS-2 cells were cultured for 24 h; or ii) post-implantation infection model, where SaOS-2 cells were first cultured for 24 h on the substrates, which were subsequently incubated for 6 h with P. aeruginosa . Actin filaments were stained with Alexa Fluor™ 546 phalloidin (orange fluorescence signal) and the nuclei with DAPI (blue fluorescence signal). (b) Orthogonal CLSM images showing simultaneous co-visualization of cells and bacteria stained with Alexa Fluor™ 546 phalloidin (orange fluorescence signal), the nuclei with DAPI (blue fluorescence signal) and SYTO-9 (green fluorescence signal). (c) Dead percentage of P. aeruginosa onto the different CaP substrates and the controls, for both the pre-implantation infection i) and the post-implantation ii) infection models. n = 3; ns and ∗ indicate significance at p > 0.05 and p ≤ 0.05, respectively.
