Fig. 3From: In vivo Wnt pathway inhibition of human squamous cell carcinoma growth and metastasis in the chick chorioallantoic modelAnalysis of CD44 positive cells in UM-SCC-1 CAM xenografts. a Flow cytometry results of unstained sample of UM-SCC-1 primary tumor cells grown in the CAM assay. b Flow cytometry results of UM-SCC-1 primary tumor cells stained with CD44-APC antibody. 15.44Â % of the total cell population is CD44+, but only 18.97Â % of the total cell population is human cells. Therefore 81.39Â % of the UM-SCC-1 cells in the CAM xenograft are CD44+Back to article page
