From morphogenes to morphogenesis [PDF]
Summary: If the concept of organization is of such importance as it appears to be, it is something of a scandal that biologists have not yet begun to take it seriously but should have to confess that we have no adequate conception of it. The first duty of the biologist would seem to be to try and make clear this important concept.

Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we

Noise drives sharpening of gene expression boundaries in the zebrafish hindbrain
Morphogens provide positional information for spatial patterns of gene expression during development. However, stochastic effects such as local fluctuations in morphogen concentration and noise in signal transduction make it difficult for cells to ...

When it Pays to Rush: Interpreting Morphogen Gradients Prior to Steady-State
During development, morphogen gradients precisely determine the position of gene expression boundaries despite the inevitable presence of fluctuations. Recent experiments suggest that some morphogen gradients may be interpreted prior to reaching steady ...

Long‐term stability of horizontal bone augmentation at implant sites
Abstract Horizontal bone augmentation is a fundamental surgical procedure in regenerative implant dentistry. In recent decades, this procedure has evolved, enabling clinicians to achieve predictable and stable horizontal bone augmentation that supports dental implant restorations.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Continuous-time random-walk model for anomalous diffusion in expanding media
Expanding media are typical in many different fields, e.g. in Biology and Cosmology. In general, a medium expansion (contraction) brings about dramatic changes in the behavior of diffusive transport properties.

ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.
