Studying mucus biology has been challenging due to the lack of physiologically relevant human in vitro models. However, recent progress has been made in the development of human organ-on-a-chip microfluidic culture models, focusing on the lung, colon, small intestine, cervix, and vagina. These models can reconstitute epithelial tissue barriers and physiologically relevant mucus layers, allowing for the study of mucus composition, mechanics, and structure in a biomimetic environment.
The surfaces of human internal organs are lined by a mucus layer that ensures symbiotic relationships with commensal microbiome while protecting against potentially injurious environmental chemicals, toxins, and pathogens, and disruption of this layer can contribute to disease development. Studying mucus biology has been challenging due to the lack of physiologically relevant human in vitro models. Here we review recent progress that has been made in the development of human organ-on-a-chip microfluidic culture models that reconstitute epithelial tissue barriers and physiologically relevant mucus layers with a focus on lung, colon, small intestine, cervix and vagina. These organ-on-a-chip mod-els that incorporate dynamic fluid flow, air-liquid interfaces, and physiologically relevant mechanical cues can be used to study mucus composition, mechanics, and structure, as well as investigate its contri-butions to human health and disease with a level of biomimicry not possible in the past.(c) 2022 Elsevier B.V.
