MDCK (NBL-2) Cells

MDCK (Madin-Darby Canine Kidney) cells serve as a pivotal vitro model in pharmaceutical sciences, particularly in the study of epithelial transport, epithelial permeability, and as a tool for membrane permeability evaluation. These cells, originally derived from renal tubule cells of a canine, exhibit properties akin to enterocytes, making them an excellent absorption screening model and a reliable cell line for evaluating drug transport mechanisms. MDCK cells are used to explore branching morphogenesis, a process crucial for understanding organ development and cellular differentiation. This capacity for complex organization underscores their relevance in studying epithelial tissue architecture and cellular accumulation. MDCK cells are well-regarded for their ability to form tight, polarized epithelial layers, making them a valuable model for studying epithelial barrier function and cell polarity, making them an indispensable model for drug carrier systems and the study of intrinsic membrane permeability. The presence of apical membranes and well-defined cell junctions in MDCK cell monolayers facilitates detailed permeability experiments, enhancing our understanding of transepithelial secretion and the transport and metabolic functions inherent to epithelial cells. In virology, MDCK cells are pivotal for studying human influenza viruses, such as the H3N2 strain, because they express receptors compatible with those viruses. This makes them a key resource for investigating the intricacies of viral infections, examining how epithelial cells react to viral challenges. Their utility extends to evaluating antiviral agents and vaccines, further emphasizing their significance in infectious disease research and therapeutic development. In summary, MDCK cells are invaluable in pharmaceutical and virological research for their epithelial characteristics, transport studies, and utility in viral infection models, particularly for influenza viruses, making them indispensable in advancing our understanding of drug delivery, epithelial biology, and infectious diseases.
