ABSTRACT
This study examined the morphological changes of human derived bone cell cultures on polytetrafluoroethylene (PTFE) and polystyrene dishes (tissue culture plastic, Corning Glass Works, Corning, New York) during a three hour period using scanning electron microscopy. Since the material possesses a different configuration on each side, both sides were studied. The cells had a higher affinity for the more porous side of the material.
