Abstract

In this work, we design and fabricate an integrated multi-level, hydrodynamically-optimized microfluidic chip to study long-term Escherichia coli population dynamics in a microfluidic device. Our experiments show that a population of proliferating E. coli in a microchannel organizes into lanes of genetically identical cells within a few generations. This behavior can be theoretically predicted to confirm that genetic diversity is quickly lost along lanes of cells. Our findings elucidate the effect of lane formation on populations evolution, with potential applications ranging from microbial ecology in soil to dynamics of epithelial tissues in higher organisms.
