Asbestos-induced mutagenicity in the lung may involve reactive oxygen/nitrogen species (ROS/RNS) released by alveolar macrophages. With the aim of proposing an alternative in vitro mutagenesis test, a coculture system of rat alveolar macrophages (NR8383) and transgenic Big Blue Rat2 embryonic fibroblasts was developed and tested with a crocidolite sample.(More)
Antehypophysial somatotropic and prolactinic cells of the Hedgehog have isolated cilia composed by a ring of 9 or 8 double tubules with or without a central tubule; this single cilia is in relation with a basal corpuscule. A granulo-filamentous neck joins the basal corpuscule to the subjacent centriole; from this granulo-filamentous neck accompanying the(More)
Folliculo-stellar cells are present in the anterior lobe of hypophysis of the monkey Macacus irus. These cells limit strait cavities in which one can observe microvillosites at the apical pole of the cells. The folliculo-stellar cells possess long and thin fibers which insert themselves between different types of granular cells and sometimes extend to the(More)
