FITC-phalloidin staining of the actin-cytoskeleton in a human LNCaP prostate cancer cell, as seen by confocal microscopy. Active cell protrusions containing weak stress fibers are visible. Despite differences in Integrin utilization on laminin substrata, no changes were found in the appearance of actin-cytoskeleton network betweek cells with altered androgen-dependency and metastatic potential. For details see the article by Edlund et al. in this issue.
