Figure Lengend Snippet: Bar charts indicate comparison between DCC scaffold vs DCC scaffold + cells and DMB scaffolds vs DMB scaffold + cells by direct method (a). Bar charts indicate comparison between DMB conditioned media (CM) and DCC conditioned media (CM) vs complete culture media (Control) by indirect method (b). *p<0.05 is indicated. n = 4; CM: conditioned media. (c). HOB cells seeded on DMB and DCC scaffolds showing optimum cell attachment by DAPI staining. (i & iii) DMB scaffolds and (ii & iv) DCC scaffolds; images were captured by fluorescence and confocal microscopy, respectively. Scanning electron micrograph of HOB cells seeded onto DMB (d) and DCC (e) scaffolds. The osteoblast shows a healthy morphology residing on the ECM with evidence of filopodia spread (red arrows).

Figure Lengend Snippet: Photomicrographs of HOB cells stained with Alizarin Red S. HOB cells showed increased mineralized nodules in osteogenic medium (OS + ) compared to cells without supplements (OS - ). More significant mineralization was seen by day 14 (a). Quantification of alizarin Red S stained mineralized nodules in human osteoblast cells seeded on DMB and DCC scaffolds grown in the presence or absence of osteogenic induction media at days 7 and 14 in comparison to cells alone is shown; p<0.001 is indicated). The absorbance of the extracted Alizarin dye was measured at 405 nm. Data presented as mean ± SEM (n = 6) (b). Quantification of Alizarin Red S staining in osteoblast cell-seeded DMB and DCC scaffolds on day 14 in the presence and absence of osteogenic supplements. Data presented as mean ± SEM (n = 4) (c); p<0.001 is indicated.
