Keratinocyte function in extracellular proteolysis was investigated. Keratinocytes derived from rat tongue ventral epithelium were maintained and serially propagated under conditions which support continuous expansion of epithelial colonies but are restrictive to fibroblast proliferation (30–32°C and pH 6.8–7.0). These cultures, and cultures of an established, terminally differentiating keratinocyte line, also derived from the ventral epithelium of the rat tongue, released substantial plasminogen activator activity as visualized by the fibrin-agar overlay technique. In addition, keratinocytes grown directly on3H-labeled fibrin lysed this substrate in a plasmin-assisted process. The presence of serum modulated the kinetics of the reaction in a manner which suggests that a constant inhibitor tonus serves to contain the proteolytic reaction in the tissues and to prevent a chain reaction. Electrophoretic resolution of keratinocyte secretory proteins and of cell lysates revealed three distinct activators migrating at molecular weights of 48 000, 66 000 and 95 000. The keratinocytes also manufactured inhibitor(s) of the fibrinolytic reaction mainly directed against the activation step. The inhibitory activity was present in serum-free culture harvest media in quantities sufficient to completely annihilate the endogenous activators.
