Fig. 8From: Targeting CXCR4 by a selective peptide antagonist modulates tumor microenvironment and microglia reactivity in a human glioblastoma modelIn vivo effects of peptide R on U87MG glioma vascularization. CLSM analyses on brain sections of untreated (CTRL) or peptide R- or Plerixafor-treated mice for the detection of CD31 (endothelial marker, red) and VEGF (angiogenic factor, green). Images were taken both in the tumor core and in the contralateral hemisphere. Scale bars, 75 μmBack to article page
