Pharmacological Or Genetic Targeting Of Transient Receptor Potential (TRP) Channels Can Disrupt The Planarian Escape Response [PDF]

, 2019
In response to noxious stimuli, planarians cease their typical ciliary gliding and exhibit an oscillatory type of locomotion called scrunching. We have previously characterized the biomechanics of scrunching and shown that it is induced by specific ...

Comparative analysis of septic injury-inducible genes in phylogenetically distant model organisms of regeneration and stem cell research, the planarian Schmidtea mediterranea and the cnidarian Hydra vulgaris

Frontiers in Zoology, 2008
Background The planarian Schmidtea mediterranea and the cnidarian Hydra vulgaris have emerged as valuable model organisms in regeneration and stem cell research because of their prominent ability to regenerate a complete organism from any small body ...

NF-YB Regulates Spermatogonial Stem Cell Self-Renewal and Proliferation in the Planarian Schmidtea mediterranea. [PDF]

PLoS Genetics, 2016
Gametes are the source and carrier of genetic information, essential for the propagation of all sexually reproducing organisms. Male gametes are derived from a progenitor stem cell population called spermatogonial stem cells (SSCs).

MELATONIN STIMULATES PHOTORECEPTOR DIFFERENTIATION IN REGENERATION OF PLANARIAN SCHMIDTEA MEDITERRANEA

THEORY AND PRACTICE OF PARASITIC DISEASE CONTROL, 2023
The planarian Schmidtea mediterranea (Turbellaria, Platyhelminthes) has a pair of eyes on the anterior part of the body consisting of pigment cells and photoreceptor neurons capable of regeneration.

Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.

Evolutionary history of the Tricladida and the Platyhelminthes: an up-to-date phylogenetic and systematic account [PDF]

, 2012
Within the free-living platyhelminths, the triclads, or planarians, are the best-known group, largely as a result of long-standing and intensive research on regeneration, pattern formation and Hox gene expression.

Embryonic origin of adult stem cells required for tissue homeostasis and regeneration

eLife, 2017
Planarian neoblasts are pluripotent, adult somatic stem cells and lineage-primed progenitors that are required for the production and maintenance of all differentiated cell types, including the germline.

Constitutive gene expression and the specification of tissue identity in adult planarian biology [PDF]

, 2011
Planarians are flatworms that constitutively maintain adult tissues through cell turnover and can regenerate entire organisms from tiny body fragments.

A comparative analysis of planarian genomes reveals regulatory conservation in the face of rapid structural divergence

Nature Communications
The planarian Schmidtea mediterranea is being studied as a model species for regeneration, but the assembly of planarian genomes remains challenging.

A functional genomics screen in planarians reveals regulators of whole-brain regeneration

eLife, 2016
Planarians regenerate all body parts after injury, including the central nervous system (CNS). We capitalized on this distinctive trait and completed a gene expression-guided functional screen to identify factors that regulate diverse aspects of neural ...
