on the basis of both 125i-labeled plasminogen activator binding analysis and transmission electron microscopy studies of the interaction of a plasminogen activator/gold complex with cell membranes , we have found that human keratinocytes have specific receptors for human urokinase-type plasminogen activator distributed on the cell surface as singlets , or as small or large clusters .
