Phase Transitions, Interfaces, and Morphogenesis in a Network of Protein Fibers

1994
Publisher Summary This chapter presents results obtained in a model tissue system. The system consists of liquid drops containing assembling fibers of type I collagen, which under appropriate conditions exhibit the phenomenon of matrix-driven translocation (MDT). This system is based, in part, on materials from the extracellular matrix of mesenchymal

Mathematical modeling of the first phase of morphogenesis of mechanoreceptors in D. melanogaster

Journal of Applied and Industrial Mathematics, 2012
The mechanoreceptors (in particular, macrochaetes) of drosophila pass three stages in its development (morphogenesis) whose genetic support is described in terms of gene networks. The key object of the gene networks of macrochaete morphogenesis is the achaete-scute (AS-C) complex of genes.

Reconstructing the aeolian processes in Daurian steppes during arid phases of morphogenesis

Geography and Natural Resources, 2015
Regional characteristics of aeolian morphogenesis in steppes of Central Asia have been ascertained on the basis of summarizing experimental field data, the results from studying the profiles of Holocene deposits and interpreting space-acquired images as well as disembodied published data. It is shown that the Onon-Torei Plain has the role of an aeolian

Time-lapse X-ray phase-contrast microtomography for in vivo imaging and analysis of morphogenesis

Nature Protocols, 2014
X-ray phase-contrast microtomography (XPCμT) is a label-free, high-resolution imaging modality for analyzing early development of vertebrate embryos in vivo by using time-lapse sequences of 3D volumes. Here we provide a detailed protocol for applying this technique to study gastrulation in Xenopus laevis (African clawed frog) embryos.

A mechanistic understanding of biofilm morphogenesis: Coexistence of mobile and sessile aggregates and phase-separated patterns

2022
AbstractMost bacteria in the natural environment self-organize into collective phases such as cell clusters, swarms, patterned colonies, or biofilms. The occurrence of different phases and their coexistence is governed by several intrinsic and extrinsic factors such as the growth, motion, and physicochemical interactions.

Phase-Field Based Simulations of Embryonic Branching Morphogenesis

2017
While the study of the embryonic organ development is an active research field, many of the fundamental questions regarding the emergence of shape and growth control remain unanswered. Mathematical modelling stands as a powerful tool to help investigate morphogenesis dynamics during embryonic development.

Phase dependent thermal and spectroscopic responses of Al₂O₃nanostructures with different morphogenesis

Nanoscale, 2015
In this review, we discuss new developments and recent trends in both amorphous and crystalline Al2O3 oxide nanofluids related to their phase dependent characteristics in detail. Nowadays, nanofluids have gained significant attention with the enhanced energy/heat efficiency, which is highly desirable to improve the performance of any energy based ...

Cyclic Adenosine 3'5‘ Monophosphate (c‐AMP) as a Factor in Phase Morphogenesis of Blastomyces dermatitidis

Mycoses, 1984
Summary: The intracellular concentration of cyclic adenosine 3'5′ monophosphate (c‐AMP) was found to be 1.3 times higher in the mycelium of Blastomyces dermatitidis than that found in its yeastlike growth form. Yeastlike cells of the fungus grown at the preferential temperature of 37°C reverted to mycelial phase growth in the presence of the c‐AMP ...

Morphogenesis and wall chemistry of the yeast, "intermediate," and hyphal phases of the dimorphic fungus, Mycotypha poitrasii

Canadian Journal of Microbiology, 1980
When Mycotypha poitrasii(Zygomycetes) is grown under standard conditions in liquid culture containing 1% polypeptone, 0.5% yeast extract, and variable glucose concentrations (0–6%), it displays mycelial–yeast conversion. "Intermediate" cells, isolated from cultures containing 2% glucose, are considered to represent a developmental phase in the process
