A CFSE-Based Assay to Monitor Skin Dendritic Cell Migration to Draining Lymph Nodes in Infected Mice
Abstract
Source: Bollampalli, V. P., et al. A CFSE-based Assay to Study the Migration of Murine Skin Dendritic Cells into Draining Lymph Nodes During Infection with Mycobacterium bovis Bacille Calmette-Guérin. J. Vis. Exp. (2016)
This video demonstrates an assay for monitoring dendritic cell migration following footpad infection with Mycobacterium bovis Bacille Calmette-Guérin BCG in mice. Upon bacterial infection, activated skin DC cells are labeled with a cell-permeable carboxyfluorescein diacetate succinimidyl ester (CFSE) dye. After a suitable interval for DC migration to the popliteal draining lymph node, the node cells are isolated and subjected to immunostaining for DC-specific surface markers. Identification of migrated DCs is performed using flow cytometry.
