Conduction block in micropatterned cardiomyocyte cultures replicating the structure of ventricular cross-sections.

AIMS Structural and functional heterogeneities in cardiac tissue have been implicated in conduction block and arrhythmogenesis. However, the propensity of specific sites within the heart to initiate conduction block has not been systematically explored. We utilized cardiomyocyte cultures replicating the realistic, magnetic resonance imaging-measured tissue boundaries and fibre directions of ven...

Micropatterned Co-cultures of Human Embryonic Stem Cell with Murine Embryonic Fibroblasts on Microwell Patterned Substrates

Human embryonic stem (hES) cells are generally cultured on top of a feeder layer formed by mitotically inactivated murine embryonic fibroblasts (MEFs) to maintain their undifferentiated state. The culture of hES cells in this co-culture system presents several challenges since it is difficult to control cell cluster size. Large cell clusters tend to differentiate at the borders, and clusters wi...

A Novel Toolbox for Generating Realistic Biological Cell Geometries for Electromagnetic Microdosimetry

Researchers in bioelectromagnetics often require realistic tissue, cellular and sub-cellular geometry models for their simulations. However, biological shapes are often extremely irregular, while conventional geometrical modeling tools on the market cannot meet the demand for fast and efficient construction of irregular geometries. We have designed a free, user-friendly tool in MATLAB that comb...

Mammalian cell cultures on micropatterned surfaces of weak-acid, polyelectrolyte hyperbranched thin films on gold.

A four-step soft lithographic process based on micro-contact printing of organic monolayers, hyperbranched polymer grafting, and subsequent polymer functionalization results in polymer/n-alkanethiol patterns that direct the growth and migration of mammalian cells. The functional units on these surfaces are three-dimensional cell "corrals" that have walls 52+/-2 nm in height and lateral dimensio...

Micropatterned cell co-cultures using layer-by-layer deposition of extracellular matrix components.

Micropatterned cellular co-cultures were fabricated using three major extracellular matrix components: hyaluronic acid (HA), fibronectin (FN) and collagen. To fabricate co-cultures with these components, HA was micropatterned on a glass substrate by capillary force lithography, and the regions of exposed glass were coated with FN to generate cell adhesive islands. Once the first cell type was i...
