Representative three-dimensional F-actin morphology images for BMSCs cultured with TGF-β1 supplementation and encapsulated in agarose (left column), RAD16-I (center column), and KLD12 (right column). Culture duration was (A) 0 days, (B) 4 days, or (C) 21 days. (D) High magnification, confocal images at day 21. Red indicates F-actin and blue indicates cell nuclei. Scale bar in (A) is applicable to (B) and (C), in all cases scale bar = 50 μm. Color images available online at www.liebertonline.com/ten.
