Synthetic spatial patterning in bacteria: advances based on novel diffusible signals

Microbial Biotechnology, 2022
Summary Engineering multicellular patterning may help in the understanding of some fundamental laws of pattern formation and thus may contribute to the field of developmental biology.

Developmental gene regulatory networks in sea urchins and what we can learn from them [version 1; referees: 3 approved]

F1000Research, 2016
Sea urchin embryos begin zygotic transcription shortly after the egg is fertilized.  Throughout the cleavage stages a series of transcription factors are activated and, along with signaling through a number of pathways, at least 15 different cell types ...

Fetal functional brain age assessed from universal developmental indices obtained from neuro-vegetative activity patterns. [PDF]

PLoS ONE, 2013
Fetal brain development involves the development of the neuro-vegetative (autonomic) control that is mediated by the autonomic nervous system (ANS). Disturbances of the fetal brain development have implications for diseases in later postnatal life.

Dynamics of cell polarity in tissue morphogenesis: a comparative view from Drosophila and Ciona [version 1; referees: 2 approved]

F1000Research, 2016
Tissues in developing embryos exhibit complex and dynamic rearrangements that shape forming organs, limbs, and body axes. Directed migration, mediolateral intercalation, lumen formation, and other rearrangements influence the topology and topography of ...

A ClearSee-Based Clearing Protocol for 3D Visualization of Arabidopsis thaliana Embryos

Plants, 2021
Tissue clearing methods combined with confocal microscopy have been widely used for studying developmental biology. In plants, ClearSee is a reliable clearing method that is applicable to a wide range of tissues and is suitable for gene expression ...

Curvature-driven spatial patterns in growing 3D domains: A mechanochemical model for phyllotaxis. [PDF]

PLoS ONE, 2018
Here we discuss the formation of phyllotactic patterns in the shoot apical meristem (SAM) of plants, where the spatial distribution of the phytohormone auxin determines phyllotaxis in a domain that is growing and changing in time.

Avian Pigment Pattern Formation: Developmental Control of Macro- (Across the Body) and Micro- (Within a Feather) Level of Pigment Patterns

Frontiers in Cell and Developmental Biology, 2020
Animal color patterns are of interest to many fields, such as developmental biology, evolutionary biology, ethology, mathematical biology, bio-mimetics, etc. The skin provides easy access to experimentation and analysis enabling the developmental pigment

Regulatory Network of the Scoliosis-Associated Genes Establishes Rostrocaudal Patterning of Somites in Zebrafish

iScience, 2019
Summary: Gene regulatory networks govern pattern formation and differentiation during embryonic development. Segmentation of somites, precursors of the vertebral column among other tissues, is jointly controlled by temporal signals from the segmentation ...

Signaling to stomatal initiation and cell division

Frontiers in Plant Science, 2014
Stomata are two-celled valves that control epidermal pores whose opening and spacing optimizes shoot-atmosphere gas exchange. Arabidopsis stomata formation undergoes at least one asymmetric division and a symmetric division.

Gene copy number and negative feedback differentially regulate transcriptional variability of segmentation clock genes

iScience, 2022
Summary: Timely progression of a genetic program is critical for embryonic development. However, gene expression involves inevitable fluctuations in biochemical reactions leading to substantial cell-to-cell variability (gene expression noise). One of the
