studies in rapidly growing versus quiescent l , early passage/late passage wi-38 cells , suggest accumulation of fluorescence schiff bases ( i.e. , their association with granular regions of cells in stationary phase , spectral properties , fast increase in photosensitized cells ) and a possible lysosomal membrane permeabilization in quiescent or senescent cells .
