FIG. 7.

Col-III synthesis inside the HA–Ge hydrogel at the (A) zero time point, (B) after 7 days in the control with CCM flow perfusion and without phonation, and (C) after 7 days of culture in the bioreactor with phonation. Col-III and cell nuclei are stained in green and blue, respectively. All the images were captured by using a 20 × objective. (A−C) Scale bar is 50.0 μm. (D) Picture of the Col-III synthesis in the phonated sample with higher magnification (20 × , zoom = 10). Col-III, collagen type III. Color images available online at www.liebertpub.com/tec
