Figure 9. Optical micrographs of the live fibroblast cells at wells adjacent to the PEG-impregnated BA scaffolds sintered at 900 and 1000°C derived from the three different femoral sections at day-1 (A – PEG-D900, B – PEG-M900, C – PEG-P900, D – PEG-D1000, E – PEG-M1000, and F – PEG-D1000), day-4 (G – PEG-D900, H – PEG-M900, I – PEG-P900, J – PEG-D1000, K – PEG-M1000, and L – PEG-D1000), and day-7 (M – PEG-D900, N – PEG-D1000, O – PEG-M900, P – PEG-M1000, Q – PEG-P900, and R – PEG-P1000) just before the AB assay.

Figure 9

Images of (S) negative control or blank (only medium in well, without cell and scaffold) and (T) positive control (only medium and cells in well, without scaffold) wells after day 7 are presented for comparison. All the scale bars are 50 µm. Amount of live cell concentration is higher in the wells for the PEG-treated scaffolds sintered at 1000°C compared to 900°C.
