Dryg expression in regenerated sexual planarians
following exposure to BPA or E2 after ablation
"The fact that the marker we discovered is expressed not only in planarians
but also in humans suggests that there are some conserved mechanisms that we can exploit.
Evolution and regeneration of the planarian
central nervous system.
exhibited normal gliding behavior (Figure 1(a)), which was quantified as spontaneous planarian
The collection of the freshwater planarian
Dugesia gonocephala (Duges, 1830), took place in the Guacollo River at the town of Visviri, Parinacota, Chile (17[degrees]35' 42.99"S and 69028' 56.86"; 4100masl) during January 2010.
"Human counterparts exist for most of the genes that we have found to regulate the activities of planarian
stem cells," said Sanchez Alvarado.
He pinpointed the locations of stem cells and studied how far they dispersed using RNA whole-mount in situ hybridization (WISH), specifically adapted to planarians
in Sanchez Alvarado's lab.
Endemic and exotic land planarians
in the United States with a discussion of necessary changes in the Rhynchodemidae.
(OK, it's not likely to work with an earthworm, but planarians
are excellent candidates for this experiment.) Biology offers just as many fun surprises as physics does.
, a type of flatworm, are the lowest form of life that possesses an integrated neural network organized in a manner that many consider to represent the earliest brain.
Pax6 related genes have been found in all bilateria analyzed so far, ranging from planarians
This fact is an important neuroevolutionary advance, since we did not observe inhibitory synapses in planarians
, neither in annelids (Palacios-Pru et al.
