| vasa-related genes and their expression in stem cells of colonial parasitic rhizocephalan barnacle polyascus polygenea (arthropoda: crustacea: cirripedia: rhizocephala). | vasa (vas)-related genes are members of the dead-box protein family and are expressed in the germ cells of many metazoa. we cloned vasa-related genes (ppvlg, cpvlg) and other dead-box family related genes (ppdrh1, ppdrh2, cpdrh, atdrhr) from the colonial parasitic rhizocephalan barnacle polyascus polygenea, the non-colonial clistosaccus paguri (crustacea: cirripedia: rhizocephala), and the parasitic isopodan athelgis takanoshimensis (crustacea: isopoda). the colonial polyascus polygenea, a paras ... | 2007 | 17085060 |
| [morphofunctional organization of reserve stem cells providing for asexual and sexual reproduction of invertebrates]. | published and original data indicating evolutionary conservation of the morphofunctional organization of reserve stem cells providing for asexual and sexual reproduction of invertebrates are reviewed. stem cells were studied in representatives of five animal types: archeocytes in sponge oscarella malakhovi (porifera), large interstitial cells in colonial hydroid obelia longissima (cnidaria), neoblasts in an asexual race of planarian girardia tigrina (platyhelmintes), stem cells in colonial rhizo ... | 2009 | 19405444 |
