Following the VITROCELL® User Group Meeting 2018 in San Antonio, Texas, USA, international scientists from Europe, Japan, Korea and USA reconvened in March 2019.

The informal event organized into short presentations and posters was followed by open discussions. It was an excellent opportunity to discuss the latest developments of VITROCELL®, to exchange your experience in working with the equipment and to meet other fellow researchers.
The meeting took place prior to the international Society of Toxicology 58th Annual Meeting and ToxExpo, March 10 – 14, 2018, in Baltimore, USA - one of the largest international conferences related to toxicology.

Focus of the event was to share VITROCELL® activities since the last meeting, to exchange latest research results, to give an update on VITROCELL’s participation in major research programs as well as the presentation of new products for 2019.

The Vitrocell® Cloud-6 system was used for the exposure of a coculture in vitro model to test compounds and vehicle controls. The 3D in vitro model was cultured at the air liquid interface consists of A549, EA.hy926, PMA-differentiated THP-1 and non-differentiated THP-1 cells, that were exposed to nebulized chemical respiratory sensitizers. The results are shown in flow cytometry measurements, cytokine release and gene expression.

The distribution and impact of aerosol-delivered functionalized AuNPs upon repeated administration were explored in a complex in vitro human lung epithelial tissue barrier model applying an air–liquid interface exposure approach. Nanoparticles were aerosolized using the Air-Liquid Interface system consisting of a nebulizer, an exposure and an incubation chamber connected to an air-flow system to provide optimum conditions for cell cultivation as well as a quartz crystal microbalance for online measurements of the NP dose deposited on the cells surface.
