Pre-clinical assays, including in vitro assays, rely heavily on suppliers who provide essential products or services. In the current regulatory environment, the burden is placed on the users of these products or services to ensure that the methods employed at the suppliers' facilities meet a sufficient level of quality. Variable results for the same assay controls over time could indicate high lot-to-lot variability of the test system or of critical assay components.

Human precision-cut lung slices (hPCLS), considered a highly relevant ex vivo model of the lung, offer native architecture and cells of the lung tissue including respiratory parenchyma, small airways, and immune competent cells. However, the irregular availability of donor lungs has limited the accessibility of this system. As described here, thousands of hPCLS can be created from 1 lung, cryopreserved, and used “on demand” by applying slicing and cryopreservation methodology improvements.

Exhaled or side-stream cigarette smoke (CS) may visually stain a consumer’s skin over time. Tobacco heating prod- ucts (THPs) and e-cigarettes (ECs) have reduced staining potential because they do not produce side-stream aerosols and their exhaled aerosols have significantly reduced levels of toxicants, particles and odour. Here we assess discolour- ation of porcine skin in vitro after exposure to particulate matter (PM) or aerosols from CS (3R4F), two THPs (glo and glo sens) and an EC (iSwitch Maxx).

IIVS is excited to announce a new publication in Science with co-authors at Boston University and Mechanobiologix (Newton, MA, USA)! Abstract: Emphysema is a debilitating disease that remodels the lung leading to reduced tissue stiffness. Thus, understanding emphysema progression requires assessing lung stiffness at both the tissue and alveolar scales.
