SEARCH FOR DIFFERENTIAL GENE EXPRESSION IN THE JELLYFISH AURELIA AURITA
I. V. Matveev
Institute of Cytology, RAS, St. Petersburg, Russia;
The body of Aurelia aurita, as well as other diploblasts, consists of two epithelial layers: ectodermal
and gastral epithelium. These two tissues are separated by mesoglea, or extracellular matrix. In most coelenterates mesoglea is
acellular. In A. aurita mesogleal cells are scattered in mesoglea. Differential display PCR was used to compare mRNA pools
from ectodermal epithelium, gastral epithelium and mesoglea. 4 novel gene fragments were cloned and sequenced. According to
RTPCR results, one of these fragments is differentially expressed in the ectodermal epithelium.
