Scaling and regeneration of self-organized patterns [PDF]
, 2015 Biological patterns generated during development and regeneration often scale with organism size. Some organisms, e.g., flatworms, can regenerate a rescaled body plan from tissue fragments of varying sizes.

Nature Communications, 2018 The Mll3/4 histone methyltransferases can act as tumour suppressors in humans. Here, the authors identify three orthologs of mammalian MLL3/4 in the planarian Schmidtea mediterranea and show that knockdown causes outgrowths in regenerating animals ...

Developmental defects in planarian hatchlings (Platyhelminthes: Rhabditophora) [PDF]
Zoologia (Curitiba)Developmental plasticity of the planarians is well-illustrated by whole-body regeneration from any tissue fragments and body size scaling regulated by food intake.

Tryptophan hydroxylase Is Required for Eye Melanogenesis in the Planarian Schmidtea mediterranea. [PDF]
PLoS ONE, 2015 Melanins are ubiquitous and biologically important pigments, yet the molecular mechanisms that regulate their synthesis and biochemical composition are not fully understood.

Transcriptional signatures of somatic neoblasts and germline cells in Macrostomum lignano [PDF]
, 2009 The regeneration-capable flatworm Macrostomum lignano is a powerful model organism to study the biology of stem cells in vivo. As a flatworm amenable to transgenesis, it complements the historically used planarian flatworm models, such as Schmidtea ...

Germline Defects Caused by Smed-boule RNA-Interference Reveal That Egg Capsule Deposition Occurs Independently of Fertilization, Ovulation, Mating, or the Presence of Gametes in Planarian Flatworms. [PDF]
PLoS Genetics, 2016 Few animals are known to lay eggs in the absence of ovulation or copulation, as it is presumably energetically wasteful and subjected to negative selection.

Fate specification is spatially intermingled across planarian stem cells
Nature Communications, 2023 Regeneration requires mechanisms for producing a wide array of cell types. Neoblasts are stem cells in the planarian Schmidtea mediterranea that undergo fate specification to produce over 125 adult cell types.
