Planarian neoblast micronucleus assay for evaluating genotoxicity

Chemosphere, 2008
Planarian neoblasts are somatic stem cells that have the potential to be used in genotoxicity assays due to their proliferative nature, sensitivity to genotoxic agents, and experimental accessibility. Two freshwater planarian species, Girardia tigrina and Girardia schubarti, were used to develop a neoblast-based micronucleus (MN) assay to assess ...

Neoblasts and the evolution of whole-body regeneration

Current Opinion in Genetics & Development, 2016
The molecular mechanisms underlying whole-body regeneration are best understood in the planarian flatworm Schmidtea mediterranea, where a heterogeneous population of somatic stem cells called neoblasts provides new tissue for regeneration of essentially any missing body part.

Cytological studies on the planarian neoblast

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1959
The paper is a study of the cytology of the regeneration cells (neoblasts) in Planaria vitta. The morphology of the living cells has first been examined to provide a reference for an investigation of the fixed neoblasts as studied by ordinary cytological, cytochemical and electron microscopical technics.

Distribution of the stem cells (neoblasts) in the planarian Dugesia japonica

Development Genes and Evolution, 2005
It has been postulated that the high regeneration ability of planarians is supported by totipotent stem cells, called neoblasts. There have been a few reports showing the distribution of neoblasts in planarians. However, the findings were not completely consistent.

A cytological and quantitative study of neoblasts in the naidOphidonais serpentina (Oligochaeta)

Wilhelm Roux' Archiv f�r Entwicklungsmechanik der Organismen, 1974
The fine structure of the neoblasts in the naidOphidonais serpentina has been examined. The neoblasts of control worms have a relatively large nucleus, containing a large nucleolus, a sparse amount of rough endoplasmic reticulum, and an abundance of free ribosomes and mitochondria.
