Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Evaluation of the genotoxic and teratogenic potential of a municipal sludge and sludge-amended soil using the amphibian Xenopus laevis and the tobacco: Nicotiana tabacum L. var. xanthi Dulieu [PDF]
The toxic, genotoxic and teratogenicpotential of amunicipal sewage sludge was assessed using the micronucleus assay on the larvae of the amphibianXenopuslaevis and with the tobacco somatic mutation test using the yellow–green xanthiDulieu mutant a1+/a1 ...

Genetic code expansion for chemosensing and chemical actuation of biological functions
Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.

Identification of a Candidate CD5 Homologue in the Amphibian Xenopus laevis [PDF]
We identified a novel T cell Ag in the South African clawed toad (Xenopus laevis) by a mAb designated 2B1. This Ag is present in relatively high levels on most thymocytes, approximately 65% of splenocytes, 55% of PBL, and 65% of intestinal lymphocytes ...

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Acquisition of Leftward Flow in Xenopus laevis
In Xenopus, the left-right axis is established following an extracellular vectorial leftward flow driven by monocilia at the gastrocoel roof plate (GRP) during late gastrulation / neurulation (Schweickert et al., 2007).

The distribution of Dishevelled in convergently extending mesoderm [PDF]
Convergent extension (CE) is a conserved morphogenetic movement that drives axial lengthening of the primary body axis and depends on the planar cell polarity (PCP) pathway.

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Fish and amphibians as test organisms for evaluation of effects caused by chemicals [PDF]
A large number of chemicals can contaminate aquatic environments and therefore be exposed to fish and amphibians during their sensitive stages of development.

Oocyte maturation in the toad Rhinella arenarum (Amphibia, Anura): Evidence of cAMP involvement in steroid production and action [PDF]
In this work, we describe the participation of the adenylate cyclase/3′-5′-cyclic adenonsine monophosphate (cAMP) pathway in the seasonal follicular secretion of progesterone (P 4 ) and testosterone (T), and its relationship with the maturation of ...
