Supplementary Fig 7 - Collagen fibrous scaffolds for sustained delivery of growth factors for meniscal tissue engineering

Supplementary Figure 7. Representative histologic images of ex vivo repair: H&E, Safranin O/fast green, collagen type I immunostaining, PDGFRb immunostaining, and DAPI. (Note this is the 10x mag. view of histologic slides in Figure 7) Surgically created tears implanted with (a) Control = unconjugated collagen scaffolds, (b) HCOL = heparin conjugated collagen scaffolds, (c) PDGF-BB, (d) TGFb1, or (e) CTGF coated on heparin conjugated collagen scaffolds. (Mag. 10x; scale bar: 200 µm). All constructs were cultured for 3 weeks and then processed for histology.
