Visualization of Motor Axon Navigation and Quantification of Axon Arborization In Mouse Embryos Using Light Sheet Fluorescence Microscopy Ee Shan Liau*1,2, Ya-Ping Yen*2,3, Jun-An Chen1,2 1Molecular and Cell Biology, Taiwan International Graduate Program, Academia Sinica and Graduate Institute of Life Sciences, National Defense Medical Center, 2Institute of Molecular Biology, Academia Sinica, 3Institute of Biotechnology, College of Bio-Resources and Agriculture, National Taiwan University Here, we describe a protocol for visualizing motor neuron projection and axon arborization in transgenic Hb9::GFP mouse embryos. After immunostaining for motor neurons, we used light sheet fluorescence microscopy to image embryos for subsequent quantitative analysis. This protocol is applicable to other neuron navigation processes in the central nervous system.
Cell Lineage Analyses and Gene Function Studies Using Twin-spot MARCM Hung-Chang Shen1,2, Tsai-Chi Hsu1, Pei-Chi Chung1, Hung-Hsiang Yu1,2 1Institute of Cellular and Organismic Biology, Academia Sinica, 2Graduate Institute of Life Sciences, National Defense Medical Center Here, we present a protocol for a mosaic labeling technique that permits the visualization of neurons derived from a common progenitor cell in two distinct colors. This facilitates neural lineage analysis with the capability of birth-dating individual neurons and studying gene function in the same neurons of different individuals.
Assessment of the Immunomodulatory Properties of Human Mesenchymal Stem Cells (MSCs) Pei-Ju Hsu1, Ko-Jiunn Liu2, Ying-Yin Chao1, Huey-Kang Sytwu3, B. Linju Yen1 1Regenerative Medicine Research Group, Institute of Cellular & System Medicine, National Health Research Institutes (NHRI), 2National Institute of Cancer Research, National Health Research Institutes (NHRI), 3Institute of Microbiology & Immunology, National Defense Medical Center The immunomodulatory properties of human mesenchymal stem cells (MSC) appear increasingly relevant for clinical application. Using a co-culture system of MSCs and peripheral blood leukocytes pre-stained with the fluorescent dye carboxyfluorescein succinimidyl ester (CFSE), we describe the in vitro assessment of MSC immunomodulation on effector leukocyte proliferation and specific subpopulations.
