Neoblast Specialization in Regeneration of the Planarian Schmidtea mediterranea

Planarians can regenerate any missing body part in a process requiring dividing cells called neoblasts. Historically, neoblasts have largely been considered a homogeneous stem cell population. Most studies, however, analyzed neoblasts at the population rather than the single-cell level, leaving the degree of heterogeneity in this population unresolved. We combined RNA sequencing of neoblasts fr...

The freshwater planarian Schmidtea mediterranea: embryogenesis, stem cells and regeneration.

Planarians have been used as a model to study development and regeneration for more than 200 years. Research on these animals has traditionally focused on surgical and pharmacological manipulations. Recently, the dissection of planarians has become more molecular in nature. The isolation of thousands of expressed sequence tags and the introduction of in situ hybridizations, immunocytology, and ...

Ammonia excretion in the freshwater planarian Schmidtea mediterranea.

In aquatic invertebrates, metabolic nitrogenous waste is excreted predominately as ammonia. Very little is known, however, of the underlying mechanisms of ammonia excretion, particularly in freshwater species. Our results indicate that in the non-parasitic freshwater planarian Schmidtea mediterranea, ammonia excretion depends on acidification of the apical unstirred layer of the body surface an...

A premeiotic function for boule in the planarian Schmidtea mediterranea.

Mutations in Deleted in Azoospermia (DAZ), a Y chromosome gene, are an important cause of human male infertility. DAZ is found exclusively in primates, limiting functional studies of this gene to its homologs: boule, required for meiotic progression of germ cells in invertebrate model systems, and Daz-like (Dazl), required for early germ cell maintenance in vertebrates. Dazl is believed to have...

05-P016 DNA methylation in the freshwater planarian Schmidtea mediterranea

(Shaked etal., PLoS ONE 2008). To further investigate this finding, several different approaches have been taken. First, the expression of HDAC-regulated candidate genes responsible for controlling neurogenesis has been examined through quantitative realtime RT-PCR. TSA-based inhibition of HDAC activity resulted in upregulation of Bmp2, Stat1, Stat3, Ngn1 and Ngn2 in neural precursors from both...
