Indirect immunofluorescent images, of NIH-3T3 cells ,murine fibroblasts,, were acquired by confocal microscopy.  Focal adhesions, shown in red, are the cellâ??s anchoring points.  Fibrillar adhesions, shown in green, translocate out of focal adhesions pulling fibronectin molecules ,extracellular matrix protein,, thus facilitating fibrillogenesis.  Cell nuclei are shown in blue. X63
