have the ability to regenerate any organ, as determined by the presence of totipotent stem cells in the stroma.
are much simpler making them ideal model systems to study regeneration.
Dubois, a French scientist, who first developed the techniques for partially irradiating planarians
Endemic and exotic land planarians
in the United States with a discussion of necessary changes in the Rhynchodemidae.
This fact is an important neuroevolutionary advance, since we did not observe inhibitory synapses in planarians
, neither in annelids (Palacios-Pru et al.
Interestingly, the S100 proteins are highly conserved in amino acid composition among vertebrate species (22), and S100-like proteins have also been immunologically detected in planarians
and spinach leaves (23, 24).
The remaining planarians
were then placed in the train-a-tray, one at a time, to reverse their bias by shocking them until they went the other way 415 times or 80% The shock average for the control group was 3.
Entire groups have shown evolutionary radiation into a large number of endemic species (snails and slugs, earthworms, planarians
, butterflies, beetles, etc).
Some land planarians
of the United States and Europe, with remarks on nomenclature.
This does not differ greatly from the pelagic formation of Lake Michigan, which includes copepods, cladocerans, roundworms, planarians
, and leeches.
The origin of infertility in the hyperplasic ovary of ex-fissiparous planarians
remains poorly understood.
