In Vitro Culture and Differentiation of Primary Monocytes into Macrophages

Samenvatting

Source: Plaisance-Bonstaff, K., et al. Isolation, Transfection, and Culture of Primary Human Monocytes. J. Vis. Exp. (2019)

This video demonstrates the priming of primary monocytes into macrophages. Primary human monocytes can be isolated and differentiated to an M1-like pro-inflammatory phenotype using the granulocyte-macrophage colony-stimulating factor (GM-CSF) or to an M2-like anti-inflammatory phenotype using the macrophage colony-stimulating factor (M-CSF).

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.

1. Isolation of primary human monocytes by immunomagnetic negative selection

1. Collect 40 mL of fresh, human whole blood (from either an HIV⁺ patient or healthy control) in four 10 mL ethylenediaminetetraacetic acid (EDTA) vacuum tubes (10 mL of blood per tube). Using sterile techniques under a biosafety cabinet, transfer all 40 mL of blood into one 50 mL conical propylene tube.<....
