Generation of Aligned Functional Myocardial Tissue Through Microcontact Printing

1Cardiovascular Research Center, Massachusetts General Hospital and Harvard Medical School, 2Harvard Stem Cell Institute


JoVE 50288

The generation of aligned myocardial tissue is a key requirement for adapting the recent advances in stem cell biology to clinically useful purposes. Herein we describe a microcontact printing approach for the precise control of cell shape and function. Using highly purified populations of embryonic stem cell derived cardiac progenitors, we then generate anisotropic functional myocardial tissue.

Creating Adhesive and Soluble Gradients for Imaging Cell Migration with Fluorescence Microscopy

1Centre for Vascular Research and Australian Centre for Nanomedicine, The University of New South Wales, 2School of Chemistry and Australian Centre for Nanomedicine, The University of New South Wales


JoVE 50310

A method for the assembly of adhesive and soluble gradients in a microscopy chamber for live cell migration studies is described. The engineered environment combines antifouling surfaces and adhesive tracks with solution gradients and therefore allows one to determine the relative importance of guidance cues.

Creating Two-Dimensional Patterned Substrates for Protein and Cell Confinement

1Department of Chemistry, Washington University in St. Louis


JoVE 3164

Self-assembled monolayers (SAMs) formed from long chain alkane thiols on gold provide well-defined substrates for the formation of protein patterns and cell confinement. Microcontact printing of hexadecanethiol using a polydimethylsiloxane (PDMS) stamp followed by backfilling with a glycol-terminated alkane thiol monomer produces a pattern where protein and cells adsorb only to the stamped hexadecanethiol region.

Soft Lithographic Functionalization and Patterning Oxide-free Silicon and Germanium

1Department of Chemistry, Duke University, 2Hajim School of Engineering and Applied Sciences, University of Rochester, 3Department of Chemical Engineering, University of Rochester


JoVE 3478

Here we describe a simple method for patterning oxide-free silicon and germanium with reactive organic monolayers and demonstrate functionalization of the patterned substrates with small molecules and proteins. The approach completely protects surfaces from chemical oxidation, provides precise control over feature morphology, and provides ready access to chemically discriminated patterns.

A Microfluidic Chip for the Versatile Chemical Analysis of Single Cells

1Department of Chemistry and Applied Biosciences, ETH Zurich, Switzerland


JoVE 50618

In this article we present a microfluidic chip for single cell analysis. It allows the quantification of intracellular proteins, enzymes, cofactors, and second messengers by means of fluorescent assays or immunoassays.

Studying Cell Rolling Trajectories on Asymmetric Receptor Patterns

1Department of Materials Science and Engineering, MIT - Massachusetts Institute of Technology, 2Department of Mechanical Engineering, MIT - Massachusetts Institute of Technology, 3HST Center for Biomedical Engineering and Harvard Stem Cell Institute, Brigham and Women's Hospital and Harvard Medical School


JoVE 2640

We describe a protocol to observe and analyze cell rolling trajectories on asymmetric receptor-patterned substrates. The resulting data are useful for engineering of receptor-patterned substrates for label-free cell separation and analysis.

Micropatterned Surfaces to Study Hyaluronic Acid Interactions with Cancer Cells

1Department of Chemical and Biomolecular Engineering, Johns Hopkins Physical Sciences Oncology Center and Institute for NanoBioTechnology, Johns Hopkins University


JoVE 2413

A novel approach that allows the high-resolution analysis of cancer cell interactions with exogenous hyaluronic acid (HA) is described. Patterned surfaces are fabricated by combining carbodiimide chemistry and microcontact printing.

Cell Patterning on Photolithographically Defined Parylene-C: SiO2 Substrates

1Centre for Integrative Physiology, School of Biomedical Sciences, The University of Edinburgh, 2Edinburgh Cancer Research Centre, Institute of Genetics and Molecular Medicine, Western General Hospital, 3School of Engineering, Institute for Integrated Micro and Nano Systems, The University of Edinburgh


JoVE 50929

This protocol describes a microfabrication-compatible method for cell patterning on SiO2. A predefined parylene-C design is photolithographically printed on SiO2 wafers. Following incubation with serum (or other activation solution) cells adhere specifically to (and grow according to the conformity of) underlying parylene-C, whilst being repulsed by SiO2 regions.

Cell Co-culture Patterning Using Aqueous Two-phase Systems

1Department of Biomedical Engineering, University of Michigan, 2Department of Macromolecular Science and Engineering, University of Michigan


JoVE 50304

Aqueous two-phase systems were used to simultaneously pattern multiple populations of cells. This fast and easy method for cell patterning takes advantage of the phase separation of aqueous solutions of dextran and polyethylene glycol and the interfacial tension that exists between the two polymer solutions.
