FIGURE 7:

High-density HLFs deposit treated with TGF-β1 deposit more collagen matrix. (A) Representative immunostained images of COL1A1 (green) and the nucleus (blue). (B) Representative images of COL1A1 staining for collagen-coated and fibronectin-coated slides. Scale bar on fibronectin-coated slide image represents 10 µm and applies to all images in panels A and B. (C) Fluorescence integrated density values from immuno­staining images. Each dot in the dot plot represents the mean value of one sample and the center lines represent the median values. *p < 0.05, **p < 0.01, ***p < 0.001.
