MOLUSKUEN LISERI-GURUINEKO EPITELIOAREN ... - Euskara

gutxi batzutara baino ez da iristen. Eskualde
horretan animaliek kinada fotikoak eta gorantz zein
beherantzko mareen pauta erritmikoak ere jasotzen
dituzte. Ondorioz, marea-erritmoa liseri-sistemaren
zelulen proliferazioaren prozesu erritmikoak
gobernatzeko Zeitgeber perfektua izan daiteke,
kasu honetan bezala muskuiluak mareazpikoak
badira ere.
Laburbilduz, liseri-zeluletan irudi mitotikoak
behatu izanak eta BrdUren emaitzek, zelulen
berriztapena liseri-guruineko zelula helduen
zatiketa autologoaren bitartez gauzatzen dela
egiaztatu dute. Urdaileko eta liseri-unitate
albeolotubularreko epitelioek, zelulen berriztapen-
tasa ertaina eta altua bitarteko dute. Epitelio-zelulen
berriztapena sinkronizatuta dago, 24 ordutan 2 ziklo
osoak betetzen dituen patroi zirkamareala jarraituz.
