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.

20th International Congress on In Vitro Toxicology (ESTIV2018)

October 15–18, 2018. Germany, Berlin. Booth #26

The general theme of the Congress is “New approach methodologies for in vitro toxicology applications”. This slogan is fully reflected in the 8 thematic sessions to which you can submit abstracts for oral or poster presentation. Abstract authors will be invited to prepare an original research manuscript or review paper to be taken into consideration for the ESTIV2018 proceedings that will be published in the journal Toxicology In Vitro.

ACE nano: pursuing analytical and characterisation excellence in nanomaterial risk assessment

Nanomaterials are man-made materials of a size thousands of times smaller than the width of a human hair. They have fascinated scientists and industry with their unique and unpredictable properties, which have given rise to an endless variety of new applications in every sector of technology and medicine. As a result, an ever-increasing number of nanomaterials are entering the market in everyday products spanning from healthcare and leisure to electronics, cosmetics and foodstuffs. However, the novelty in exploitable properties may be mirrored by new hazards and, in order to manage these, a well-founded and robust legislative framework that will ensure safe development of nano-enabled products is needed.

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.

In this study two innovative in vitro techniques were combined: The Vitrocell® Powder Chamber and the human cell based MucilAir™ system. Their combined use allows the investigation of the effect of aerosolized pollen and appropriate drugs on a human mucosal tissue, a similar scenario finding in humans. The release of pro-inflammatory cytokines (IL-6, IL-8, and TNF-α) was quantified as an initial cellular response to pollen contact and to confirm the protective effect of drugs.
