Assessing the Development of Murine Plasmacytoid Dendritic Cells in Peyer’s Patches Using Adoptive Transfer of Hematopoietic Progenitors

Overview

This protocol describes experimental procedures to assess the differentiation of plasmacytoid dendritic cells in Peyer��s patch from common dendritic cell progenitors. Techniques include FACS-mediated cell isolation, hydrodynamic gene transfer, and flow analysis of immune subsets.
