Differentiation of Macrophages from PBMC monocytes

Materials

  • Sterile 50mL conical tubes
  • 24 or 96 well flat bottom tissue culture plates
  • Sterile PBS
  • RPMI 1640 (10% FBS, 1%pen/strep)
  • Human M-CSF (Peprotech)

Procedure

All work should be done inside a cell culture hood

  • Isolate mononuclear cells from buffy coats
  • Dilute cells to 2*106cell/mL in RPMI
  • Plate in 96 (100μL) or 24 (660μL) well flat bottom tissue culture plates
  • Let monocytes adhere for 2-4 hours in 37°C 5%CO2 incubator
  • Wash cells 3 times with PBS
  • Add RPMI supplemented with 50ng/mL M-CSF and return to incubator
  • Replace media with M-CSF supplemented RPMI every 2-3 days
  • Macrophages will be ready after 7 days of culture

Macrophage validation

  • Cells should have high cytoplasm/nucleus size ratio
  • Stain cells for several key markers of macrophages and immature monocytes
    • Should have high CD68, some CD14, no CD1a
