The timing of replication of mouse ribosomal RNA (rRNA) genes was determined in cultured cells by using 5-bromodeoxyuridine labeling of DNA coupled with synchronization. Two subclasses of rRNA genes were characterized that differ in their temporal order of replication during S-phase. Approximately half of the rDNA repeat units replicated primarily during(More)
In order to use microporous membranes as a culture substratum for later air/liquid exposures with human pulmonary fibroblasts, we were interested to find out whether the behaviour of cells grown on PET membranes differs from those cultured under conventional conditions. We therefore compared cytoskeletal structures of membrane-adherent and glass-adherent(More)
