Figure 7. Collagen SHG of HDF-seeded constructs at day 21.

Figure 7

SHG images of collagen matrix deposited on random and aligned scaffolds were obtained at day 21 at different depths. SHG intensity and area coverage is greater at all depths than the equivalent depths at day 14 suggesting increased collagen deposition and organisation. For images taken at 75–100 µm on both scaffolds, laser power was set to maximum in order to see any SHG present. Arrow indicates direction of scaffold fibre alignment. Scale bars are 50 µm.
