In visualization, using the right texture for a piece of furniture, the proper material for an interior, or the appropriate plants for an exterior design can have a huge impact on the final product. Similarly, using human figures that accurately represent activities and demographics in these virtual settings can affect how we perceive the scale and nature of spaces in digital images.
Design Connected can be handy for those looking to create details and realistic interior settings. While a majority of their database is made up of paid furniture models and textures, they also have a nice selection of free 3D models that include lighting fixtures, wall art, furniture and other décor objects. In addition to their paid subscriptions, they also offer a student discount for those enrolled in full-time architecture, design and fine arts programs.
The website caters to designers from a variety of industries including architecture, interior design and gaming. They offer several kinds of free 3D models that can be used in different softwares. This database includes sofa sets, cars, fantasy characters and even fictional city blocks. Furthermore, the platform also allows designers to sell their own 3D models and earn royalties.
The toxicological assessment of drugs and particles following exposure by inhalation has long relied on in vivo studies6,7. However, the limited number of compounds that can be tested, the interspecies variability, the associated cost and ethical concerns have supported the development of alternative in vitro models of the human upper and lower airways8,9,10. Functional bronchial epithelium models were developed to investigate the toxicity and translocation of various agents11,12. These models have greatly promoted our understanding of the epithelial response and supported the identification of the adverse outcome pathways of toxic compounds.
The available models of the human bronchial epithelium using cell lines can be used to study acute toxicity following short-term exposure, usually 24 or 48 h13,14. However there is a lack of functional models to investigate the long-term toxicity of drugs or pollutants following chronic exposure or repeated exposure at low doses. The difficulties associated with long-term cell cultures (without subculturing) are decreased cell viability, divergence and changes in cellular features, and stratification due to continuous proliferation. The development of in vitro lung models to investigate the chronic toxicity of exogenous agents by inhalation is therefore a key step in the field of predictive toxicology.
The human Calu-3 lung adenocarcinoma cell line (ATCC HTB-55) is an interesting alternative to primary cells for the development of robust and low-cost models of the human bronchial epithelium for toxicological assessment. The Calu-3 cells differentiate into a functional tight epithelium when cultured on inserts at ALI. Even though the resulting epithelium is limited to one cell type, it exhibits features specific to the human bronchial epithelium such as a tight epithelial barrier, mucus secretion, receptor expression, and cytokine production among others9,18,19,20,21,22,23. Expert panels and pre-validation assays have put forward the Calu-3 model of the bronchial epithelium for drug screening24,25,26. Readers may refer to reviews for more details about this cell line25,27,28,29. Other lung cell lines could be used as in vitro models, such as the epithelial BEAS-2B, NCI-H292, and 16HBE cell lines30,31,32. Contrary to BEAS-2B, NCI-H292, and 16HBE, the Calu-3 cell line can simultaneously form a tight epithelium at ALI and secrete mucus33. Hence, we selected the Calu-3 cell line for this study.
The objectives of this study were to develop a preclinical model of the human bronchial epithelium using the Calu-3 cell line for chronic toxicity study with minimal FBS supplementation, and to characterize the time evolution of the epithelial cell secretions. The Calu-3 cells were maintained for 21 days at ALI without subculturing and showed good viability and functionality, making it a relevant model for chronic toxicity studies of inhaled drugs, particles or pollutants. Here, we adapted the Calu-3 model for long-term nanotoxicology studies for repeated and chronic exposure to inhaled NPs by culturing cells on inserts with a 3-µm pore diameter. A larger pore size allows the analysis of NP translocation through the epithelial barrier9. Compared to primary cell models, the main advantages of the Calu-3 model are the availability, low cost, absence of donor variability, and the formation of a tight epithelium on inserts with a 3-µm pore diameter with excellent barrier properties without addition of any drug15,21,22,67. In comparison, the growth of NHBE cells is not possible on membranes with such a large porosity, and is limited to inserts with a 0.4-µm pore diameter. The disadvantages of the Calu-3 model are the presence of only one cell type, an abnormal karyotype, and the growth of polyps in certain conditions (data not shown). Some differences in anion secretion during transepithelial fluid transport were also reported28. 2ff7e9595c
