Abstract

Microfluidic devices have become a promising alternative approach for cellular co-culture. Many approaches incorporate a semipermeable barrier to physically separate, yet chemically connect, two cell types; however, the majority of these approaches utilize batch culture conditions which can result in nutrient depletion and waste accumulation. This chapter describes an alternative approach that allows for the continuous infusion of media, relieving the constraints of batch culture. The microfluidic device consists of two separate layers: a bottom layer of 3% (w/v) agarose to facilitate chemical diffusion and a top polydimethylsiloxane (PDMS) layer into which four parallel fluidic channels were imprinted. The microfluidic approach allows for facile visualization of cells with light microscopy and the ability to add (or subtract) drugs or biomolecules to interrogate the system or modulate the cellular response. Finally, the approach allows for terminal immunostaining of either (or both) cell types.
