Role As A Model Organism
Long ignored as an exotic, marginal phenomenon, Trichoplax adhaerens is today viewed as a potential biological model organism. In particular, research is needed to determine how a group of cells that cannot be considered full-fledged epithelial tissue organizes itself, how locomotion and coordination occur in the absence of true muscle and nerve tissue, and how the absence of a concrete body axis affects the animal's biology. At the genetic level, the way in which Trichoplax adhaerens protects against damage to its genome needs to be studied, particularly with regard to the existence of special DNA-repair processes. Complete decoding of the genome should also clarify the placozoans' place in evolution, which continues to be controversial.
In addition to basic research, this animal could also be suitable for studying wound-healing and regeneration processes; as yet unidentified metabolic products should be researched. Finally, Trichoplax adhaerens is also being considered as an animal model for testing compounds.

Famous quotes containing the words role as, role, model and/or organism:
“American feminists have generally stressed the ways in which men and women should be equal and have therefore tried to put aside differences.... Social feminists [in Europe] ... believe that men and society at large should provide systematic support to women in recognition of their dual role as mothers and workers.”
—Sylvia Ann Hewitt (20th century)
“The most puzzling thing about TV is the steady advance of the sponsor across the line that has always separated news from promotion, entertainment from merchandising. The advertiser has assumed the role of originator, and the performer has gradually been eased into the role of peddler.”
—E.B. (Elwyn Brooks)
“I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorf’s, Bendel’s, Bonwit’s, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.”
—Estelle Shuster (b. c. 1923)
“Apathy is one of the characteristic responses of any living organism when it is subjected to stimuli too intense or too complicated to cope with. The cure for apathy is comprehension.”
—John Dos Passos (1896–1970)
