Macrophages maintain tissue homoeostasis by regulating inflammation and tissue repair mechanisms. Thus, the fate of macrophages has an impact on the state of the tissue. The aim of this protocol is to quantify macrophage survival using high content microscopy and image processing software. Here, we describe a high-content image based protocol to assess the effect of diverse stimuli in combination with pharmacological treatments on macrophage survival in a quantitative, unbiased and high-throughput manner.
