Fig. 4From: Metastatic breast cancer cells induce altered microglial morphology and electrical excitability in vivoAbsence of human nuclear antigen-positive cells at the lesion site. Confocal image at 20x of microglia (green), human nuclear antigen (HNA; magenta) and nuclei (blue) in coronal section obtained from a Cx3cr1GFP/+ mouse killed 6 days following implantation of tumour cells under the imaging window. A positive control MDA-MB-231 orthotopic mammary xenograft tumour section showed strong HNA staining (data not shown). Scale bar, 50 μmBack to article page
