*3.7.1. Picrosirius red staining (PSR)*

Graphical representation of PSR stain absorbance is shown in **Figure 8**. Higher absorbance indicates greater collagen content secreted by osteoblasts on the scaffolds. All test groups supported collagen production and throughout the length of the experimental period. On average, a higher amount of collagen synthesis was observed on day 14 stain as compared to day 7. However, there was no significant difference in the amount of collagen synthesized among all the groups on given day.
