Relationship between Flower Color and Cellular Physicochemical Factors in Bletilla striata

Horticulturae, 2023
Flower color not only determines the quality and commercial value of ornamental plants, but it also plays a vital role in ecological processes such as pollinator attraction.

3D time series analysis of cell shape using Laplacian approaches [PDF]

, 2013
Background: Fundamental cellular processes such as cell movement, division or food uptake critically depend on cells being able to change shape. Fast acquisition of three-dimensional image time series has now become possible, but we lack efficient tools

Deciphering the roles of cell shape and Fat and Dachsous planar polarity in arranging the Drosophila apical microtubule network through quantitative image analysis [PDF]

, 2023
In epithelial cells, planar polarisation of subapical microtubule networks is thought to be important for both breaking cellular symmetry and maintaining the resulting cellular polarity.

Cell-Responsive Shape Memory Polymers

, 2022
Recent decades have seen substantial interest in the development and application of biocompatible shape memory polymers (SMPs), a class of “smart materials” that can respond to external stimuli.

Tight Regulation of Mechanotransducer Proteins Distinguishes the Response of Adult Multipotent Mesenchymal Cells on PBCE-Derivative Polymer Films with Different Hydrophilicity and Stiffness

Cells, 2023
Mechanotransduction is a molecular process by which cells translate physical stimuli exerted by the external environment into biochemical pathways to orchestrate the cellular shape and function.

Chemotaxis: a feedback-based computational model robustly predicts multiple aspects of real cell behaviour [PDF]

, 2011
The mechanism of eukaryotic chemotaxis remains unclear despite intensive study. The most frequently described mechanism acts through attractants causing actin polymerization, in turn leading to pseudopod formation and cell movement.

Cell envelope growth of Gram‐negative bacteria proceeds independently of cell wall synthesis [PDF]

, 2023
International audienceAbstract All bacterial cells must expand their envelopes during growth. The main load‐bearing and shape‐determining component of the bacterial envelope is the peptidoglycan cell wall.

Getting bacterial cells into shape

eLife, 2023
The conformational state of a structural protein in bacteria can vary, depending on the concentration level of potassium ions or the nucleotide bound to it.

Cell Migration with Multiple Pseudopodia: Temporal and Spatial Sensing Models [PDF]

, 2013
Cell migration triggered by pseudopodia (or “false feet”) is the most used method of locomotion. A 3D finite element model of a cell migrating over a 2D substrate is proposed, with a particular focus on the mechanical aspects of the biological phenomenon.
