RNAi Interference by dsRNA Injection into Drosophila Embryos
Ekaterini Iordanou 1, Rachana R. Chandran 1, Nicholas Blackstone 1, Lan Jiang 1
1Department of Biological Sciences, Oakland University

RNA interference has been proven very effective to analyze gene function in Drosophila tracheal development. A detailed protocol used by Jiang lab to inject dsRNA into fly embryos to knockdown gene expression is illustrated. This technique has the potential for screening genes required for tissue and organ development in Drosophila.

Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle function.

Here, we present a protocol for the dissection of human umbilical cord (UC) and fetal placenta sample into cord lining (CL), Wharton's jelly (WJ), cord-placenta junction (CPJ), and fetal placenta (FP) for the isolation and characterization of mesenchymal stromal cells (MSCs) using the explant culture technique.

An Experimental Protocol for Studying Mineral Effects on Organic Hydrothermal Transformations
Ziming Yang 1, Xuan Fu 1
1Department of Chemistry, Oakland University

Earth-abundant minerals play important roles in the natural hydrothermal systems. Here, we describe a reliable and cost-effective method for the experimental investigation of organic-mineral interactions under hydrothermal conditions.

Immunostaining of Whole-Mount Retinas with the CLARITY Tissue Clearing Method
Elizabeth J. Alessio 1, Dao-Qi Zhang 1
1Eye Research Institute, Oakland University

Here we present a protocol to adapt the CLARITY method of the brain tissues for whole-mount retinas to improve the quality of standard immunohistochemical staining and high-resolution imaging of retinal neurons and their subcellular structures.
