Effect of the Anti C-fms Antibody on Osteoclastogenesis in Mouse Bone Marrow Cells In Vitro

Abstract

Source: Marahleh, A., et al. Effect of Anti-c-fms Antibody on Osteoclast Formation and Proliferation of Osteoclast Precursor In Vitro. J. Vis. Exp. (2019)

In this video, we demonstrate the effect of different anti-c-fms antibody concentrations on osteoclastogenesis, which is the process of osteoclast formation from osteoclast progenitors.

Protocol

1. Generation of BMM Seed 1 x 107 cells/10 mL in a 10 cm culture dish and add M-CSF 100 ng/mL. The final concentration of M-CSF is 100 ng/mL of culture medium. Incubate the culture at 37 °C, 5% CO2 for 3 days. After 3 days, remove the culture medium, wash the cells vigorously with 10 mL of phosphate-buffered saline (PBS) twice to remove non-adherent cells, add 5 mL of room temperature 0.02% trypsin-EDTA in PBS, and incubate at 37 °C, 5% CO2…
