Trichoplax adhaerens, an Enigmatic Basal Metazoan with Potential
2014Trichoplax adhaerens is an enigmatic basal animal with an extraordinarily simple morphological organization and surprisingly complex behaviors. Basic morphological, molecular and behavioral work is essential to better understand the unique and curious life style of these organisms.

Dissecting a peptidergic signaling pathway in Trichoplax adhaerens by gene silencing
Current BiologyTrichoplax adhaerens, a simple multicellular marine organism from the phylum Placozoa,1,2 is one of the most basal metazoan lineages, alongside Ctenophora, Porifera, and Cnidaria.3,4,5 With its remarkably simple body plan,6,7Trichoplax provides valuable insights into the evolution of multicellularity.8,9 Interestingly, despite lacking true tissues and ...

The cytoskeleton of the fiber cells of Trichoplax adhaerens (Placozoa)
Zoomorphology, 1986The cytoskeleton of Trichoplax adhaerens fiber cells was studied after chemical fixation, freeze-substitution, lysis of attached cells with nonionic detergents and by immunofluorescence. Cytoskeletal elements present in the cell bodies and reaching into the extensions include microtubules, intermediate filaments, 6–7 nm and 2–3 nm microfilaments.

My favorite animal, Trichoplax adhaerens
BioEssays, 2005AbstractTrichoplax adhaerens is more simply organized than any other living metazoan. This tiny marine animal looks like a irregular “hairy plate” (“tricho plax”) with a simple upper and lower epithelium and some loose cells in between. After its original description by F.E.

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1974 Abstract In the primitive metazoan, Trichoplax adhaerens, the fiber cells are responsible for the change of shape. Electron microscopy reveals connections between protoplasmic strands of neighbouring cells marked by an osmiophilic disc-like structure. Possible functions are discussed.

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1984 Abstract In contrast with the outmost uniform aspect of Trichoplax there is a clear cut differentiation between marginal and central cell territories. Dissection and transplantation as well as vital staining show that the marginal material is restricted to a seam approximately 20 μm in width, surrounding the much larger mass of central ...

Bioinformatic prediction of Trichoplax adhaerens regulatory peptides
General and Comparative Endocrinology, 2015Trichoplax adhaerens (phylum Placozoa) is a very simple organism that lacks a nervous system. However, its genome contains many genes essential for neuronal function and development. I report the results of regulatory peptide predictions for this enigmatic animal. Extensive transcriptome, genome, and predicted proteome mining allowed us to predict four

Expression pattern of the homeobox gene Not in the basal metazoan Trichoplax adhaerens
Gene Expression Patterns, 2004The homeobox gene Not is highly conserved in Xenopus, chicken and zebrafish with an apparent role in notochord formation, which inspired the name of this distinct subfamily. Interestingly, Not genes are also well conserved in animals without notochord such as sea urchins, Drosophila or even Hydra, but appear to be highly derived in mammals.

The Mesenchyme-Like Layer of the Fiber Cells of Trichoplax adhaerens (Placozoa), a Syncytium
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1995 Abstract The fiber cells of the middle layer of Trichoplax adhaerens are interconnected by slender extensions. Newly formed connections after mechanical disruption of the tissue studied in ultrathin sections revealed cytoplasmic continuity between the cell bodies, suggesting a syncytial organisation of the fiber cell layer.

Disaggregation and Reaggregation of Cells of the Primitive Metazoon Trichoplax adhaerens
Differentiation, 1979Trichoplax cells can be dispersed after the action of colchicine, vinblastine, and sea water free of divalent ions. Since lumicolchicine, which is inactive against microtubules can also cause disaggregation, the plant alkaloids are thought to be bound to components of the cell membrane involved in cellular adhesion. After washing, the cells reaggregate
