VITROCELL® sQCM 12: Data Interpretation

The Quartz Crystal Microbalance is a powerful tool for dosimetry in VITROCELL Exposure Systems. However, interpreting live-data from a sQCM can be misleading, as there is a lot going on in parallel during measurements.

Highlights

  • BEAS-2B cells were successfully exposed at ALI to primary UFPs emissions
  • PAHs-rich UFPs induced an acute cellular toxicity at low exposed dose
  • PAHs-rich UFPs activated oxidative stress and xenobiotic metabolism
  • This methodological approach offers new perspectives to evaluate different kinds of UFPs

Dynamic Fluid Flow Exacerbates the (Pro-)Inflammatory Effects of Aerosolised Engineered Nanomaterials In Vitro

The aim of this study was to develop further an established static in vitro model used to test ENP aerosol toxicology to incorporate fluid-flow dynamics. This was achieved by implementing the QuasiVivoTM system with a characterised A459_dTHP-1 coculture exposed in the Vitrocell Cloud12 to different particle samples at the ALI.

In the present study the 16HBE14o- cells were exposed in an automated exposure station at air-liquid interface conditions, using the controlled generation of carbon nanoparticles (CNP) aerosols by spark-ablation. This study reports that CNP exposure leads to decrease cystic fibrosis transmembrane conductance regulator (CFTR) expression accompanied by transcriptomic signs of oxidative stress, apoptosis and DNA damage.

This study aimed at testing the robustness and sensitivity, characterizing, and optimizing an advanced respiratory model built on human alveolar epithelial A549 cells and evaluating its response to aerosol exposure of silver NM-300K. In more detail, we compared the responses of A549 cells cultured at the ALI in the VITROCELL® 6 Cloud system in monoculture, in coculture with EA.hy926 cells, and in triculture with EA.hy926 cells and dTHP-1, and performed an interlaboratory trial across two laboratories.
