My favorite animal, Trichoplax adhaerens

BioEssays, 2005
AbstractTrichoplax 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.

Dynamic patterns in the locomotion and feeding behaviors by the placozoan Trichoplax adhaerence

Biosystems, 1999
The placozoan Trichoplax adhaerence is one of the most primitive multi-cellular organisms, and moves about accompanying perpetual changes in its shape. Changes in position, locomotion velocity and the outer shape of the organism were monitored quantitatively with use of a computer image analysis, and their dynamic patterns in free locomotion and upon ...

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.

Dissecting a peptidergic signaling pathway in Trichoplax adhaerens by gene silencing

Current Biology
Trichoplax 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 ...

Disaggregation and Reaggregation of Cells of the Primitive Metazoon Trichoplax adhaerens

Differentiation, 1979
Trichoplax 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

Long-Term Culturing of Placozoans (Trichoplax and Hoilungia)

The phylum Placozoa remains one of the least explored among early-branching metazoan lineages. For over 130 years, this phylum had been represented by the single species Trichoplax adhaerens-an animal with the simplest known body plan (three cell layers without any organs) but complex behaviors.

Expression pattern of the homeobox gene Not in the basal metazoan Trichoplax adhaerens

Gene Expression Patterns, 2004
The 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.

Functional Studies of Trichoplax adhaerens Voltage-Gated Calcium Channel Activity

2020
Trichoplax adhaerens is a member of the phylum Placozoa, an enigmatic group of benthic animals with remarkably simple morphology. While initial work on these organisms has primarily focused on their morphology and the development of genomic resources, Trichoplax has received increased attention as a model for studying the evolution of nervous and ...

Microfilaments and microtubules in isolated fiber cells of Trichoplax adhaerens (Placozoa)

Zoomorphology, 1989
Fiber cells isolated by mechanical disruption of the tissue in Ca2+-free sea water attach firmly to the substrate by discrete adhesion plaques. They are capable of forming a lamellipodium and long, slender extensions while the cell bodies remain stationary. The extensions are slowly elongated but can suddenly be withdrawn by contraction.
