  • Introduction to Mammalian Cell Culture

    Mammalian cell culture is one of the basic pillars of life sciences. Without the ability to grow cells in the lab, the fast progress in disciplines like cell biology, immunology, or cancer research would be unthinkable. This article gives an overview of mammalian cell culture systems. Mainly, they can be categorized according to their morphology, as well as cell type and organization. Moreover, you can find basic information about the correct growth conditions and what kind of microscope you need to watch your cells.

  • How to do a Proper Cell Culture Quick Check

    In order to successfully work with mammalian cell lines, they must be grown under controlled conditions and require their own specific growth medium. In addition, to guarantee consistency their growth must be monitored at regular intervals. This article describes a typical workflow for subculturing an adherent cell line with detailed illustrations of all of the necessary steps.

  • Tubulin Modifications Affect Monolayer Formation and Apical Trafficking in Epithelial Cells

    The development and maintenance of polarized epithelial cells requires the establishment of complicated subcellular machinery. We studied the role of post-translational tubulin modifications within this process. At first, the distribution of detyrosinated microtubules was assessed in MDCK cells via immunofluorescence microscopy. No preferential accumulation of tyrosinated or detyrosinated microtubules could be detected at the apical or basal cell poles in epithelial cell cysts. However, during monolayer formation, the quantities of detyrosinated tubulin increased significantly over time.

  • TIRF Microscopy of the Apical Membrane of Polarized Epithelial Cells

    Application of TIRF microscopy (Total Internal Reflection Fluorescence) allows the visualization of structures at the apical surface of polarized epithelial cells that have been hidden in conventional fluorescence microscopy images. Hence, the approach reveals new insights into the composition of this characteristic cell pole that elucidate processes in apical protein trafficking.

  • Apical Cargo Traverses Endosomal Compartments on the Passage to the Cell Surface

    Epithelial polarity is based on intracellular sorting machinery that maintains the asymmetric distribution of lipids and proteins to the cell surface. Dependent on their lipid raft affinity, newly synthesized apical polypeptides are segregated into distinct vesicle populations subsequent to the passage through the Golgi apparatus.
