Expansion of Airway Basal Cells and Generation of Polarized Epithelium
[Abstract] Airway basal stem cells are the progenitor cells within the airway that exhibit the capacity to self-renew and give rise to multiple types of differentiated airway epithelial cells. This stem cell-derived epithelium displays organized architecture with functional attributes of the airway mucosa. A protocol has been developed to culture and expand ...
Microbial Mutagenicity Assay: Ames Test
[Abstract] The Microbial mutagenicity Ames test is a bacterial bioassay accomplished in vitro to evaluate the mutagenicity of various environmental carcinogens and toxins. While Ames test is used to identify the revert mutations which are present in strains, it can also be used to detect the mutagenicity of environmental samples such as drugs, dyes, ...
Preparation of Amyloid Fibril Networks
[Abstract] Networks of amyloid nanofibrils fabricated from common globular proteins such as lysozyme and β-lactoglobulin have material properties that mimic the extracellular microenvironment of many cell types. Cells cultured on such amyloid fibril networks show improved attachment, spreading and in the case of mesenchymal stem cells improved ...
Preparation of Primary Cultures of Embryonic Rat Hippocampal and Cerebrocortical Neurons
[Abstract] This protocol aims at standardizing the procedure to obtain primary cultures of hippocampal and cerebrocortical neurons for in vitro experiments. Cultures should be prepared from cells isolated during embryonic development when neuronal precursor cells are not yet fully differentiated. This helps increasing the quality and quantity of ...
Culturing Bacteria from Caenorhabditis elegans Gut to Assess Colonization Proficiency
[Abstract] Determining an accurate count of intestinal bacteria from Caenorhabditis elegans is one critical way to assess colonization proficiency by a given bacteria. This can be accomplished by culturing appropriate dilutions of worm gut bacteria on selective or differential agarized media. Because of the high concentration of bacteria in gut ...

[Abstract] We have optimized a protocol for isolation of alveolar type II epithelial cells from mouse lung. Lung cell suspensions are prepared by intratracheal instillation of dispase and agarose followed by mechanical disaggregation of the lungs. Alveolar type II epithelial cells are purified from these lung cell suspensions through magnetic-based negative ...
Isolation and Cultivation of Primary Brain Endothelial Cells from Adult Mice
[Abstract] Brain endothelial cells are the major building block of the blood-brain barrier. To study the role of brain endothelial cells in vitro, the isolation of primary cells is of critical value. Here, we describe a protocol in which vessel fragments are isolated from adult mice. After density centrifugation and mild digestion of the fragments, ...
