| Abstract | To determine the integrity and permeability properties of the immortalized human VA10 bronchial epithelial cell line for its suitability as an in vitro drug permeation model.Cells were grown under liquid-covered culture (LCC) or air-liquid interface (ALI) culture, characterized using electron microscopy and immunostaining. Integrity was measured using transepithelial electrical resistance (TER) and permeability of fluorescein sodium (Flu-Na). General permeability was established with dextrans and model drugs and P-glycoprotein (P-gp) function determined with bidirectional flux of rhodamine-123.ALI culture resulted in 2–3 cell layers with differentiation towards ciliated cells but LCC showed undifferentiated morphology. VA10 cells formed TJ, with higher TER in LCC than ALI (∼2500 vs. ∼1200 Ω*cm$^{2}$) and Flu-Na permeability ∼1–2 × 10$^{−7}$ cm/s. ALI cultured cells expressed P-gp and distinguished between compounds depending on lipophilicity and size, consistent with previous data from Calu-3 and 16HBE14o-cell lines.ALI cultured cell layers capture the in vivo-like phenotype of bronchial epithelium and form functional cell barrier capable of discriminating between compounds depending on physiochemical properties. The VA10 cell line is an important alternative to previously published cell lines and a relevant model to study airway drug delivery in vitro. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
