Abstract

We present a simple hydrostatic-driven microfluidic system for spatiotemporal cell stimulation. We used the developed system to culture HeLa cancer cells and apply stimulation pulses of Tumor necrosis factor (TNF) as short as 10 s. Using this system, we established the concentration-dependent temporal limit of TNF-stimulated NF-kB activation in HeLa cells, and determined that a 30-seconds pulse is sufficient for full activation of NF-kB with 100 ng/ml TNF, and that a 1-min pulse is needed with 10 ng/ml TNF.
