Biofouling reduction by lantern nets exchange and its relationship with production and survival of Argopecten purpuratus in Samanco Bay, Peru

Journal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The aquaculture of Argopecten purpuratus (Peruvian scallop) is a profitable activity with positive impacts on the local economy. However, the development of biofouling on the culture lantern nets generates negative environmental impacts that affect its sustainability.

Poly (A) binding protein 2 is critical for stem cell differentiation during regeneration in the planarian Schmidtea mediterranea

Frontiers in Cell and Developmental Biology
Post-transcriptional regulation has emerged as a key mechanism for regulating stem cell renewal and differentiation, which is essential for understanding tissue regeneration and homeostasis.

Whole‐Gut Spatial Genomic Analysis Reveals Molecular Regionalization of the Differentiating Zebrafish Enteric Nervous System

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
Spatial genomic analysis of the developing enteric nervous system in zebrafish through multiplex whole mount HCR in slide identified genes that have temporal and spatial expression patterns during development. ABSTRACT The enteric nervous system (ENS) is the intrinsic nervous system of the gut and controls essential functions, such as gut motility ...

A proteomics approach to decipher the molecular nature of planarian stem cells

BMC Genomics, 2011
Background In recent years, planaria have emerged as an important model system for research into stem cells and regeneration. Attention is focused on their unique stem cells, the neoblasts, which can differentiate into any cell type present in the adult ...

Cilia Loss and Dynein Assembly Defects in Planaria Lacking an Outer Dynein Arm-Docking Complex Subunit

Zoological Science, 2020
The outer dynein arm-docking complex (ODA-DC), which was first identified in the green alga Chlamydomonas reinhardtii, is a protein complex that mediates the binding of axonemal dynein and doublet microtubules.

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

BioEssays, Volume 47, Issue 9, September 2025.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

A New Paradigm for Precision Drug Delivery in Inflammatory Bowel Disease: Effective Transfer, Enhanced Retention, and Pathology‐Targeting Treatment via Biomaterials and Engineered Platforms

MedComm – Biomaterials and Applications, Volume 4, Issue 3, September 2025.
This review presents a precision delivery paradigm for inflammatory bowel disease, centered on Effective Transfer, Enhanced Retention, and Pathology‐targeting Treatment. Biomaterials and engineered platforms facilitate effective intestinal transit, prolonged mucosal retention, and respond to pathological cues, such as oxidative stress or immune ...

PAGA: graph abstraction reconciles clustering with trajectory inference through a topology preserving map of single cells

Genome Biology, 2019
Single-cell RNA-seq quantifies biological heterogeneity across both discrete cell types and continuous cell transitions. Partition-based graph abstraction (PAGA) provides an interpretable graph-like map of the arising data manifold, based on estimating ...

A contribution to the zoogeography of neotropical land planarians

Acta Zoológica Lilloana, 2022
Of the three families of land planarians, only the Bipaliidae do not present endemic forms in the Neotropical Region, being represented by the cosmopolitan species Bipalium kewense.

The TALE class homeobox gene Smed-prep defines the anterior compartment for head regeneration.

PLoS Genetics, 2010
Planaria continue to blossom as a model system for understanding all aspects of regeneration. They provide an opportunity to understand how the replacement of missing tissues from preexisting adult tissue is orchestrated at the molecular level.
