title: Hyaluronate coat formation and cell spreading in rat fibrosarcoma cells.
abstract: Hyaluronate-containing pericellular coats have been demonstrated around rat fibrosarcoma cells by exclusion of particles (fixed red blood cells). The cell coats normally form during spreading of the rat fibrosarcoma cells subsequent to subculturing. Monensin, a drug which disrupts the Golgi and which also inhibits hyaluronate synthesis in these cells, inhibits the regeneration of these coats after hyaluronidase or trypsin treatment but does not inhibit cell spreading. Cycloheximide, a drug which inhibits protein but not hyaluronate synthesis does not prevent coat regeneration but partially inhibits cell spreading. Thus by exploiting the opposing effects of cycloheximide and monensin on coat regeneration and cell spreading, we have been able to dissociate these two phenomena.
