Make sure you answer the question: Does the planarian prefer a The effects of drug compounds on cell behavior can be conveniently tested in planaria, because regeneration is a sensitive assay for changes in proliferation, migration, differentiation, and morphogenetic cues. We documented occasional observations related to behavior in the field during collecting activities in the city of Montenegro and captured several specimens, taking them to the laboratory. Despite this interest in planarian behavior, a quantitative method to assay planarian locomotion in detail is still lacking. The average gar with rate for the planarian head was h millimeter per observation day. d Planarians are renowned for their regenerative ability due to pluripotent stem cells, as well as their peculiar photophobic response. Phototaxis. Planarians serve as a convenient experimental model for wound healing and cancer susceptibility due to the fact that they maintain bilateral symmetry as well as organ systems derived from all three germ layers (Newmark and Alvarado, 2002). model system for molecular studies of regeneration, adult stem cell regulation, aging, and behavior. The method is based on a simple experimental setup, using automated center - of - mass tracking and image analysis, making it an easily implemented alternative to current methods for screening planarian locomotion phenotypes.
