This is consistent with the previously described reduction in tumorigenesis upon CSF1R inhibition in mouse models for mammary (DeNardo et al, 2011), cervical (Strachan et al, 2013), and pancreatic (Zhu et al, 2014) carcinoma or in glioma (Pyonteck et al, 2013), or upon depletion of macrophages by a DT approach or clodronate liposomes in a wound‐induced skin cancer model (Arwert et al, 2010; Weber et al, 2016). Here, CSF1R is linked to skin cancer.
