Figure 3.

Cell number and morphologies of SCg6 cells maintained on rBM gels in the presence of antibodies against integrins. (A) SCg6 cells were maintained for 2 d on rBM, and the number of viable cells was determined by the MTT method. Means ± SD from three independent experiments are expressed as the absorbance (ABS) measured at 570 nm. Note that only minor differences in the number of viable cells were observed for the different antibody treatments. w/o, without antibody. (B–F) Micrographs of toluidine blue-stained SCg6 cells maintained for 2 d on rBM in the absence of antibodies (B) or in the presence of antibodies against α1 (C), α2 (D), α6 (E), and β1 (F) integrins are shown.
