For inhaled drugs in particular, research must focus on the safety and toxicity of treatments, as the respiratory tract is the most likely site to display signs of toxicity during inhalation studies.
The expoCube is ideal for in vitro models of inhalation toxicology. This is a novel Air Liquid Interface (ALI)/Transwell in vitro exposure system that efficiently deposits aerosols onto cells and tissues. It mimics the natural environment of lung cells more accurately than traditional submerged cell culture systems.
The ALI culture helped establish a dose-dependent response, to determine the toxicity (assessed via cell viability and metabolic activity assays).
When combined with SCIREQ’s inExpose® inhalation exposure platform, the expoCube allows researchers to integrate in vitro and in vivo models, optimizing compound usage while adhering to the 3Rs principle (replace, reduce, refine animal experiments).
