Immunohistochemical or immunofluorescent detection of endothelial cell markers (Endomucin (A) and Cd105 (Endoglin) (B)), artery markers (αSMA (C) and Elastin (D)), pericyte markers (Cspg4/Ng2 (E), Pdgfrb (F) and Sca1 (G)) and neuronal/neurite markers (β3 tubulin (H) and Gap43 (I) in control bones, MDA-MB231 xenografts, PC-3 xenografts and VCaP xenografts. (J) Immunofluorescent detection of Gap43 positive cells in proximity to Elastin positive cells in PC-3 and MDA-MB231 xenografts. Scale bar = 50 μm. (K) Quantification of percent positive staining area per field of view (FOV) for endomucin, Cd105 (Endoglin), αSMA, Alexa Fluor 633 (=Elastin), Cspg4/Ng2, Pdgfrb, Sca1, β3 tubulin and Gap43.
