Velocity alignment leads to high persistence in confined cells [PDF]
Phys. Rev. E 89, 062705 (2014), 2014 Many cell types display random motility on two-dimensional substrates, but crawl persistently in a single direction when confined in a microchannel or on an adhesive micropattern. Does this imply that the motility mechanism of confined cells is fundamentally different from that of unconfined cells?

Dielectrophoretic Immobilization of Yeast Cells Using CMOS Integrated Microfluidics
Micromachines, 2020 This paper presents a dielectrophoretic system for the immobilization and separation of live and dead cells. Dielectrophoresis (DEP) is a promising and efficient investigation technique for the development of novel lab-on-a-chip devices, which ...

A symmetry breaking mechanism for epithelial cell polarization [PDF]
Physical Review E 80 (3), 031919 (2009), 2010 In multicellular organisms, epithelial cells form layers separating compartments responsible for different physiological functions. At the early stage of epithelial layer formation, each cell of an aggregate defines an inner and an outer side by breaking the symmetry of its initial state, in a process known as epithelial polarization.

Cell decision-making through the lens of Bayesian learning [PDF]
, 2023 Cell decision-making refers to the process by which cells gather information from their local microenvironment and regulate their internal states to create appropriate responses. Microenvironmental cell sensing plays a key role in this process. Our hypothesis is that cell decision-making regulation is dictated by Bayesian learning.

Foam separation of microbial cells [PDF]
Biotechnology and Bioengineering, 1988 AbstractBatch foam separation has been employed to separate Saccharomyces carlsbergensis cells from their broth without the use of any external surface‐active agent. A model has been developed to predict the foamate cell concentration as well as the variation of cell concentration in the bulk liquid in the foam column as a function of time.

Microfluidic Devices for Blood Fractionation
Micromachines, 2011 Blood, a complex biological fluid, comprises 45% cellular components suspended in protein rich plasma. These different hematologic components perform distinct functions in vivo and thus the ability to efficiently fractionate blood into its individual ...

On cell separation with topographically engineered surfaces [PDF]
Biointerphases, 2013 Background Topographical modifications of the surface influence several cell functions and can be exploited to modulate cellular activities such as adhesion, migration and proliferation. These complex interactions are cell-type specific, therefore engineered substrates featuring patterns of two or more different ...

Phase Separation in Cell Division
Molecular Cell, 2020 Cell division requires the assembly and organization of a microtubule spindle for the proper separation of chromosomes in mitosis and meiosis. Phase separation is an emerging paradigm for understanding spatial and temporal regulation of a variety of cellular processes, including cell division.
