Regulation of ALF promoter activity in Xenopus oocytes. [PDF]
PLoS ONE, 2009 BACKGROUND:In this report we evaluate the use of Xenopus laevis oocytes as a matched germ cell system for characterizing the organization and transcriptional activity of a germ cell-specific X. laevis promoter.

Gene Structure Analysis of Chemokines and Their Receptors in Allotetraploid Frog, Xenopus laevis
Frontiers in Genetics, 2022 Chemokines, relatively small secreted proteins, are involved in cell migration and function in various biological events, including immunity, morphogenesis, and disease.

Genomics Data, 2014 Recently, using the frog Xenopus laevis as a model system, we showed that the transcription factor Rfx2 coordinates many genes involved in ciliogenesis and cell movement in multiciliated cells (Chung et al., 2014).

Nature Communications, 2017 Xenopus laevis tadpoles have maintained their ability to regenerate various organs. Here, the authors show that interleukin-11 is necessary for organ regeneration, by inducing and maintaining undifferentiated progenitors across cell lineages during ...

Changes in Oscillatory Dynamics in the Cell Cycle of Early Xenopus laevis Embryos
PLoS Biology, 2014 A quantitative study of the Xenopus laevis embryonic cell cycle reveals a transition in the first few cycles between two types of oscillator dynamics to meet two different developmental requirements that increase embryo viability.

The Melanogenic System of Xenopus laevis.
Archives of Histology and Cytology, 1998 Melanin pigments in lower vertebrates are often found in locations other than the skin, thus forming an extracutaneous pigmentary system of unknown function. The cellular and biochemical structure of this system is still poorly characterized. This paper deals with the ultrastructural and biochemical features of the melanogenic system of Xenopus laevis.

Genotoxic and stress inductive potential of cadmium in Xenopus laevis larvae [PDF]
, 2006 The present investigation evaluates the toxic potential of Cd in larvae of the frog Xenopus laevis after 12 days of exposure to environmentally relevant contamination levels, close to those measured in the river Lot (France).

How Xenopus laevis embryos replicate reliably: investigating the random-completion problem [PDF]
Phys. Rev. E 78, 041917 (2008), 2008 DNA synthesis in \textit{Xenopus} frog embryos initiates stochastically in time at many sites (origins) along the chromosome. Stochastic initiation implies fluctuations in the time to complete and may lead to cell death if replication takes longer than the cell cycle time ($\approx 25$ min).

Development of the proepicardium in Xenopus laevis [PDF]
Developmental Dynamics, 2008 AbstractThe proepicardium (PE) is an embryonic progenitor cell population, which provides the epicardium, the majority of the cardiac interstitium, the coronary vasculature and possibly some cardiomyocytes. Recent studies have documented (1) the presence of bilaterally paired PE anlagen in several vertebrates, and (2) species‐specific differences in ...
