Figure 7

Live and dead staining of internal cross-sections of control collagen scaffold without insulin (a), control collagen scaffold with 100 nM insulin supplemented in medium (b), and collagen-microbead hybrid scaffold (c) after 1 week of chondrocyte culture. Green fluorescence indicates live cells and red fluorescence dots indicate dead cells.
