Protein Transfection of Mouse Lung
Department of Medicine, St. Luke's Roosevelt Medical Center
Transgenic mice or viral vectors have been used to increase protein expression within the lung. However, these techniques are time-consuming, technically challenging and have off-target effects that can confound results. Our protein transfection protocol uses a lipid based transfection reagent and an ultrafine microsprayer to uniformly deliver active protein to lung cells.

Synthetic, Multi-Layer, Self-Oscillating Vocal Fold Model Fabrication
Department of Mechanical Engineering, Brigham Young University
The methodology for fabricating synthetic vocal fold models is described. The models are life-sized and mimic the multi-layer structure of the human vocal folds. Results show the models to self-oscillate at pressures comparable to lung pressure and demonstrate flow-induced vibratory responses that are similar to those of human vocal folds.

Mouse Embryonic Lung Culture, A System to Evaluate the Molecular Mechanisms of Branching
Saban Research Institute, Childrens Hospital Los Angeles
Early embryonic lung organ culture is a very useful system to study epithelial-mesenchymal interactions. Both epithelial and mesenchymal morphogenesis proceeds under specific conditions that can be readily manipulated in this system.

Harvesting Murine Alveolar Macrophages and Evaluating Cellular Activation Induced by Polyanhydride Nanoparticles
1Department of Chemical and Biological Engineering, Iowa State University, 2Department of Veterinary Microbiology and Preventive Medicine, Iowa State University
Herein, we describe protocols for harvesting murine alveolar macrophages, which are resident innate immune cells in the lung, and examining their activation in response to co-culture with polyanhydride nanoparticles.

Use of the EpiAirway Model for Characterizing Long-term Host-pathogen Interactions
Division of Basic Medical Sciences, Mercer University School of Medicine
This method allows characterization of extended bacterial co-culture with EpiAirways, primary human respiratory epithelial tissue grown at the air-liquid interface, a biologically relevant in vitro model. The approach can be used with any microbe that is amenable to long-term co-culture.

Isolation of Basal Cells and Submucosal Gland Duct Cells from Mouse Trachea
Department of Pediatrics, David Geffen School of Medicine at UCLA
Here we demonstrate our protocol for isolation of basal and submucosal gland duct cells from mouse tracheas. We also demonstrate the method of injecting stem cells into the dorsal mouse fat pad to create an in vivo model of submucosal gland regeneration.

Using Luciferase to Image Bacterial Infections in Mice
Microbial & Molecular Pathogenesis, Texas A&M Health Science Center
Methods for bioluminescence imaging of bacterial infections in living animals are decribed. Pathogens are modified to express luciferase allowing optical whole body imaging of infections in live animals. Animal models can be infected with luciferase expressing pathogens and the resulting course of disease visualized in real-time by bioluminescence imaging.

Pressure Controlled Ventilation to Induce Acute Lung Injury in Mice
Department of Anesthesiology, University of Colorado
A murine model for ventilator induced lung injury is an important tool to study an acute lung injury in vivo. Here, we report an easy applicable in situ model for acute lung injury using high-pressure mechanical ventilation to induce acute failure of the lung.
