Note the rounded appearance of the surface cells. Both control and experimental embryos were stained with Lugol's iodine. Pressure effects on cilia regeneration Since it is well established that high pressure interferes with microtubule polym- erization, the effects of pressure on cilia regeneration were investigated. The two parameters studied were the magnitude and the duration of pressure treatment. Embryos were deciliated by hypertonic sea water treatment and subjected to com- pression (2000-10,000 psi) for varying durations (10, 20, or 30 min). Following decompression, the lengths of the regenerating cilia were recorded and compared to controls. The regeneration delay for Arbacia embryos was found to be a func- tion of the duration of pressure treatment (Fig. 1). The onset of regeneration was delayed for 10-25 min in excess of the duration of compression. This delay.
