A. Percent of F-actin fibers exhibiting alignment within 10° and 25° of the long axis of the cell. Both BAEC and MC3T3 cells were cultured for a period of 24 h before fixing and staining. Unmodified glass, 50,100 and 300 nm silica NP-modified glass surfaces were tested. B. Percent increase in the number of F-actin fibers with alignment within 10° compared to glass surfaces.
