Update: Deposition Enhancement via Thermophoresis

User Group Meeting 2018

Dr. Dirk Brossell

Federal Institute for Occupational Safety and Health (BAuA), Unit 4.5, 10317 Berlin, Germany

The poster demonstrates the particle deposition via thermal precipitation (particle precipitation by thermophoresis) on cells hosted at the air-liquid interface (ALI).
Advantages of thermophoresis
• Diffusion-like mechanism, gentle particle deposition 
• Independent from particle size (for nanoparticles)
• Homogenous deposition density profile 
• No need to manipulate aerosol properties for deposition (charge, size)

Characterization of a Vitrocell VC1 Using Nicotine Dosimetry: An Essential Component Towards Standardised In Vitro Aerosol Exposure of Tobacco and Next Generation Nicotine Delivery Products

IIVS at SOT 2018

1Institute for In Vitro Sciences, Inc., Gaithersburg, MD; and 2British American Tobacco, Southampton, United Kingdom.

This study demonstrates successful Vitrocell VC1 aerosol generation and delivery across multiple nicotine product categories (3R4F cigarette smoke, e-liquid and THP), as characterised using nicotine as a dosimetry marker. The data suggests the VC1 can reproducibly generate and deliver tobacco product and NGP aerosols for future in vitro assessment and matches the performance of reported exposure systems.

VITROCELL® Cloud SEQ

User Group Meeting 2018

Patrick Weindl, Oliver Wisser

VITROCELL Systems GmbH, 79183 Waldkirch, Germany

The VITROCELL® Cloud SEQ represents another evolution of the well-known Cloud systems. Keeping functional process parameters according to established devices like the VITROCELL® Cloud 6, 12 or 24 it is meant to enhance those devices even further. lt offers the possibility to sequentially expose rows of inserts to create dose-response curves while keeping the concentration of nebulized liquid at the same level and the cell-cultures under highly comparable conditions.

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.

In vitro model for the prediction of respiratory sensitization of inhaled chemicals and protein allergens.

User Group Meeting 2018

Chary A.1,2, Serchi T.1, Cambier S.1, Moschini E.1, Contal S.1, Hennen J.2, Ezendam J.3, Blömeke B.2, Gutleb A.C.1
1 Department of Environmental Research and Innovation, Luxembourg Institute of Science and Technology (LIST), Luxembourg.
2 Department of Environmental Toxicology, Trier University, Germany. 3Centre for Environmental Protection,National Institute for Public Health and the Environment (RIVM), The Netherlands.

Aim
- Adapt a 3D-coculture system previously developed by us (Klein et al. 2013) allowing the study of respiratory sensitization processes by including dendritic cells, which have a crucial role in sensitization
- Find markers for the assessment of the respiratory sensitizing potential of inhaled compounds by measuring the activation of DCs as well as the release of cytokines
