Microfluidic Patterning of Protein Gradients on Biomimetic Hydrogel Substrates

This protocol describes a versatile microfluidic method to generate tethered protein gradients of virtually any user-defined shape on biomimetic hydrogel substrates. It can be applied to test, in a microenvironment of physiologically relevant stiffness, ho ...

LOCALIZED EXPRESSION OF HEAT SHOCK PROTEIN IN CELL POPULATION BY MICRO HEATER DEVICE

Jürgen Brugger, Filiz Yesilköy

This paper reports on the localized expression of heat shock proteins (HSPs) in a cell population on a micron-scale. Thermal stimulation was realized by micro heaters on cells in microfluidic channels to investigate cell-cell interactions with precise temp ...

Microfluidic encapsulation of cells in alginate particles via an improved internal gelation approach

Samin Akbari, Tohid Pirbodaghi

An improved internal gelation approach is developed to encapsulate single mammalian cells in monodisperse alginate microbeads as small as 26 mu m in diameter and at rates of up to 1 kHz with high cell viability. The cell damage resulting from contact with ...

Dynamic Persistence of Antibiotic-Stressed Mycobacteria

John McKinney, Neeraj Dhar, François Signorino-Gelo, Katrin Esther Schneider

Exposure of an isogenic bacterial population to a cidal antibiotic typically fails to eliminate a small fraction of refractory cells. Historically, fractional killing has been attributed to infrequently dividing or nondividing "persisters." Using microflui ...

Microfluidic Synthesis of Cell-Type-Specific Artificial Extracellular Matrix Hydrogels

Matthias Lütolf, Tanja Cloé Hausherr, Simone Allazetta

Droplet microfluidic technology is applied for the high-throughput synthesis via Michael-type addition of reactive, micrometer-sized poly(ethylene glycol) (PEG) hydrogels (“microgels”) with precisely controlled dimension and physicochemical properties. A v ...

Increasing PCR sensitivity by removal of polymerase inhibitors in environmental samples by using dielectrophoresis

Philippe Renaud, Rodrigo Martinez Duarte

Dielectrophoresis (DEP) is a powerful tool to manipulate cells and molecules in microfluidic chips. However, few practical applications using DEP exist. An immediate practical application of a carbon- electrode DEP system, in removing PCR inhibitors from a ...

Microtechnologies to Map the Fate of Single Stem Cells and their Progeny

Stefan Kobel

Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...

Highly controlled electrofusion of individually selected cells in dielectrophoretic field cages

Claus Duschl

The prospect of novel therapeutic approaches has renewed the current interest in the fusion of rare cells, like stem cells or primary immune cells. While conventional techniques are only capable of mass fusion, lab-on-a-chip systems often still lack an acc ...

Hydrogel Microfluidics to Control Stem Cell Fate

Steffen Cosson

Biomolecular signaling is of utmost importance in governing many biological processes such as morphogenesis during tissue development where biomolecules regulate key cell-fate decisions. In vivo, these factors are presented in a spatiotemporally tightly co ...

Single-Cell Analysis of Mycobacterial Persistence Using Microfabricated Tools

Meltem Elitas

Bacterial cells behave as individuals despite being genetically identical and subject to the same environment. Although the underlying mechanisms of cellular individuality are not well understood, temporal variation of gene expression and protein levels in ...
