Here we present a protocol which characterizes the sense of agency developed over the control of sensate virtual or robotic prosthetic hands. Psychophysical questionnaires are employed to capture the explicit experience of agency, and time interval estimates (intentional binding) are employed to implicitly measure the sense of agency.

Differentiation of Monocytes into Phenotypically Distinct Macrophages After Treatment with Human Cord Blood Stem Cell (CB-SC)-Derived Exosomes
Wei Hu 1,2, Xiang Song 1, Haibo Yu 1, Jingyu Sun 2, Yong Zhao 1
1Center for Discovery and Innovation, Hackensack Meridian Health Center, 2Department of Chemistry and Chemistry Biology, Stevens Institute of Technology

Exosome application is an emerging tool for drug development and regenerative medicine. We establish an exosome isolation protocol with high purity to isolate exosomes from novel identified stem cells called CB-SC for mechanistic studies. We also coculture CB-SC-derived exosomes with human monocytes, leading to their differentiation into phenotypically distinct macrophages.

3D Culturing of Organoids from the Intestinal Villi Epithelium Undergoing Dedifferentiation
Christina Li 1, Jeel Shah 1, Kylee Wrath 1, Dahlia Matouba 1, Connor Mills 1, Kishore Punnath 2, Ansu Perekatt 1
1Department of Biology and Chemical Biology, Stevens Institute of Technology, 2Department of Pharmacology, Pennsylvania State University College of Medicine

The procedure describes isolation of the villi from the mouse intestinal epithelium undergoing dedifferentiation to determine their organoid forming potential.

Separation of Follicular Cells and Oocytes in Ovarian Follicles of Zebrafish
Wenyi Wang 1, Tao Kang 1, Lin Bai 1, Wei Hu 2, Yayoi Obata 3, Jianzhen Li 1
1College of Life Sciences, Northwest Normal University, 2State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, 3Department of Bioscience, Tokyo University of Agriculture

Here, we present a simple method for separating follicular cells and oocytes in zebrafish ovarian follicles, which will facilitate investigations of ovarian development in zebrafish.

Bioengineering

Imaging-Guided Bioreactor for Generating Bioengineered Airway Tissue
Seyed Mohammad Mir 1, Jiawen Chen 1, Meghan R. Pinezich 1, John D. O’Neill 3, Brandon A. Guenthart 4, Gordana Vunjak-Novakovic 2, Jinho Kim 1
1Department of Biomedical Engineering, Stevens Institute of Technology, 2Department of Biomedical Engineering, Columbia University, 3Department of Cell Biology, State University of New York Downstate Medical Center, 4Department of Cardiothoracic Surgery, Stanford University

The protocol describes an imaging-enabled bioreactor that allows the selective removal of the endogenous epithelium from the rat trachea and homogenous distribution of exogenous cells on the lumen surface, followed by long-term in vitro culture of the cell-tissue construct.
