The complexity of next-generation tobacco products has increased by a number of factors since FDA was given responsibility to regulate tobacco. Testing e-liquids with animals is not practical, economically and not that accurate. The Vitrocell system generates airborne materials from test products, such as smoke from reference cigarettes and vapor from e-cigarettes, in a manner that simulates how a person would puff. This artcile shows, how IIVS scientists use human donor tissues, obtained from organs, to create cell cultures and in vitro test systems.

The article shows the successfull qualification of the Vitrocell VC10 smoking robot. The robot was used to  expose bacterial cells to cigarette whole smoke generated from 3R4F reference cigarettes and Eclipse cigarettes. A comparison was made between whole smoke from a tobacco heating and a combustible cigarette.

The study shows an assessment of VC1 aerosol generation that was conducted by measuring puff-by-puff in vitro nicotine concentration of 3R4F cigarettes (ISO and HCI regimes), e-cigarette (CRM81 puffing profile), and THP (HCIm regime). The aerosols were applied to in vitro or ex vivo cellular and tissue systems that model the respiratory tract, such as reconstructed human airways (RHuA), which are grown at the air–liquid interface (ALI). Additionally a comparison between the Vitrocell VC1 (U.S. Laboratory) and the VC10 (UK Laboratory) Smoking Robot was done.

This study investigated the in vitro mutagenicity of e-cigarettes and designed a study to deliver e-cigarette aerosol on an undiluted per puff basis under extreme testing conditions, using the Ames assay across a broader range of bacterial tester strains. The Vitrocell VC 10 smoking robot, previously used to generate and dilute cigarette smoke aerosols was modified to enable the testing of an undiluted e-cigarette aerosol.
