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.

Unintentional exposure of respiratory mucosal surfaces to DHA aerosols is highly possible during sunless tanning sessions, a possibility for which it is not approved. In this study, the potential respiratory toxicity of DHA using the ALI airway tissue model is evaluated. To mimic in vivo exposure conditions, a liquid aerosol generation and exposure system was used and exposed ALI cultures to a range of non-cytotoxic doses of DHA aerosols at the air-liquid interface.

New Products at VITROCELL® User Group Meeting 2018

10 March 2018, Grand Hyatt San Antonio, Texas, USA

Following the VITROCELL® User Group Meeting 2017 in Baltimore, international scientists from Canada, Europe, Japan and USA reconvened in March 2018.

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 57th Annual Meeting and ToxExpo, March 11 – 15, 2018, in San Antonio, 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 2018.
