Whole-genome sequence of the planarian Dugesia japonica …
2022年3月1日 · Dugesia japonica (D. japonica) is a typical freshwater planarian of the phylum Platyhelminthes that inhabits in East Asia [3]. This planarian can regenerate complete animals from tiny fragments in as little as 1–2 weeks [[4], [5], [6]]. This remarkable regeneration capability requires adult pluripotent stem cells known as neoblasts [7, 8].
Overview of life cycles in model species of the genus Dugesia ...
2013年8月12日 · The seven Dugesia model species represent an example of transition states between sexual and asexual reproduction. The Dugesia case contributes to the modelling of reproductive patterns and strategies in basal Metazoa as a continuum from sexual to asexual reproduction and vice versa, rather than a simple clear-cut alternative.
The molecular logic for planarian regeneration along the anterior ...
2013年7月24日 · The planarian Dugesia japonica can regenerate a complete individual from a head, trunk or tail fragment via activation of somatic pluripotent stem cells 1,2.
Different classes of small RNAs are essential for head regeneration …
2020年12月7日 · In this study, we applied high throughput sequencing to identify miRNAs, tRNA fragments and piRNAs that are dynamically expressed during head regeneration in Dugesia japonica. We further show that knockdown of selected small RNAs, including three novel Dugesia-specific miRNAs, during head regeneration induces severe defects including abnormally ...
Evolutionary dynamics of whole-body regeneration across …
2023年10月19日 · Dugesia sicula, a temperature-sensitive species, was cut at room temperature. The resulting amputation fragments were grouped according to body axis position and maintained in Petri dishes or...
Identification and characterization of a - Wiley Online Library
2020年10月20日 · Here, we used a planarian Dugesia japonica model and identified an fgf gene termed Djfgf, which encodes a putative secreted protein with a core FGF domain characteristic of the FGF8/17/18 subfamily in bilaterians.
Freshwater planarian diversity (Platyhelminthes: Tricladida: …
2017年7月10日 · Dugesia granosa is characterized by the presence of the following features: asymmetrical openings of the oviducts, with the left oviduct opening into the common atrium; presence of well-developed ectal reinforcement, extending from the vaginal area almost to the copulatory bursa; conical penis papilla; central course of the ejaculatory duct ...
Not your father's planarian: a classic model enters the era of
2002年3月1日 · At the molecular level, the first germ-line markers to be identified in planarians were a receptor tyrosine kinase (DjPTK1) 57 and two vasa-like genes (DjvlgA and DjvlgB) from Dugesia japonica 58.
Distribution of the stem cells (neoblasts) in the planarian Dugesia ...
2005年1月19日 · In this study, we cloned a cDNA encoding PCNA from the planarian Dugesia japonica, produced an antiserum against the gene product and analyzed the distribution of proliferating cells in intact and regenerating organisms. We also examined whether the PCNA-positive cells were true neoblasts or not, and we discuss the distribution of neoblasts in ...
Determination in regenerating tissues of Dugesia dorotocephala…
The present study shows that induction of normal body proportions in Dugesia dorotocephala can occur and is effective at any time through eight days of regeneration, since nerve cord grafts fused with the lateral pieces as late as after eight days of regeneration still prevented the ‘head-hump syndrome’. Head differentiation could be ...
