Bidirectional Wnt signaling between endoderm and mesoderm confers tracheal identity in mouse and human cells

open access: yesNature Communications, 2020
How murine tracheal mesenchyme is specified during development is unclear. Here, the authors show a Wnt pathway target, Tbx4, is needed but this is regulated by Wnt signals from neighbouring tracheal epithelial cells, and take advantage of this knowledge

The Impact of Intraspecies Variability on Growth Rate and Cellular Metabolic Activity of Bacteria Exposed to Rotating Magnetic Field

open access: yesPathogens, 2021
Majority of research on the influence of magnetic fields on microorganisms has been carried out with the use of different species or different groups of microorganisms, but not with the use of different strains belonging to one species.

Classification of In Vitro Phage–Host Population Growth Dynamics

open access: yesMicroorganisms, 2021
The therapeutic use of bacteriophages (phage therapy) represents a promising alternative to antibiotics to control bacterial pathogens. However, the understanding of the phage–bacterium interactions and population dynamics seems essential for successful ...

Optimal Scaling of Critical Size for Metamorphosis in the Genus Drosophila

open access: yesiScience, 2019
Summary: Juveniles must reach a critical body size to become a mature adult. Molecular determinants of critical size have been studied, but the evolutionary importance of critical size is still unclear.

Human iPS cell-engineered three-dimensional cardiac tissues perfused by capillary networks between host and graft

open access: yesInflammation and Regeneration, 2018
Stem cell-based cardiac regenerative therapy is expected to be a promising strategy for the treatment of severe heart diseases. Pluripotent stem cells enabled us to reconstruct regenerated myocardium in injured hearts as an engineered tissue aiming for ...

The Dynamics of Smithian Growth [PDF]

open access: yesThe Quarterly Journal of Economics, 1997
This paper analyzes the evolution of an economy where growth is driven by increased specialization caused by the geographical expansion of markets. It proves that such Smithian growth exhibits generic threshold behavior. Below a critical density of transport linkages, the economy is split into isolated local markets with limited specialization.
