This video demonstrates an in vitro assay to generate plasmacytoid dendritic cells (pDCs) from common lymphoid progenitor cells (CLPs). Upon co-culturing purified CLPs with γ-irradiated feeder cells in the presence of Fms-like tyrosine kinase-3 ligand (FL), the CLPs differentiate into non-adherent pDCs, the presence of which is confirmed using flow cytometry.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation of AC-6 Feeder cells Note: The AC-6.21 (AC-6 in short) stromal cell line (provided by I. Weissman, Stanford University) should be maintained in RPMI supplemented with 15% heat-inactivated fetal bovine serum (FBS). To serve as feeder cells, AC-6 cells are γ-irradiated with …
