This poster shows the investigation how aerosols are delivered within the Cloud SEQ 24 and how cell cultures respond to exposures in the system. Ibuprofen and Bortezomib was exposed to three dimensional organotypic tissue cultures of the human bronchial epithelium and biological endpoints were measured: Cytotoxicity, Interleukin 8 and Proteasome activity.

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.
