we found that stereociliary bundles of hair cells contain 80,000-98,000 micron of actin filament , i.e. , the concentration of actin is constant in all hair cells with a range of values that is less than our error in measurement and/or biological variation , the greatest variation being in relating the diameters of the stereocilia to filament number .
