Research

Our laboratory investigates the role of mechanical forces on physiology, function and disease. In particular, we are interested in understanding the interaction between structure and mechanics in regulating biological responses at different length-scales.

We employ micro- and nano-fabrication tools to recreate the cellular and tissue environment in the laboratory. We also utilize live imaging, cell/tissue mechanics and tissue engineering techniques to understand several cardio and cerebrovascular bioengineering problems including cardiac valve calcification, valve fusion and blood-brain barrier dysfunction. Knowledge gained from these studies will help guide the development of medical interventions and regenerative therapies.

Development of a nasal airway-on-chip co-culture model to study particulate matter exposure

Amanda Walls, Adrienne Vaughan & Kartik Balachandran

Particulate matter (PM) is a major component of urban air pollution and is strongly associated with respiratory diseases. However, the mechanisms of PM-induced inflammation remain poorly understood due to a lack of physiologically-relevant airway models which can incorporate PM exposure. To address this, we used our nasal airway-on-chip platform to establish a co-culture model of human nasal epithelial cells and human pulmonary microvascular endothelial cells and used this model to investigate the effects of PM exposure on the nasal airway. In particular, we sought to understand the PM-induced reactive oxygen species (ROS)-mediated inflammatory response of the co-culture. Upon PM exposure, we observed a significant increase in ROS production consistent with oxidative stress-mediated injury. Additionally, treatment with the ROS scavenger N-acetyl-cysteine attenuated ROS levels and showed a trend toward reduced inflammation, suggesting a protective effect. These findings support the utility of our model for studying PM-induced airway inflammation in a more physiologically-relevant environment.
