Fig. 1From: In vivo Wnt pathway inhibition of human squamous cell carcinoma growth and metastasis in the chick chorioallantoic modelCAM xenografted UM-SCC cell lines metastasize to the liver. This figure compares the relative content human DNA in the tissue as determined by amplified human Alu DNA sequences. The values were calculated by comparing the Alu qPCR cycle threshold (Ct) of a given liver specimen to the organs of non-xenografted control animals. Each qPCR reaction was completed in quadruplicate. Error bars are standard error of the meanBack to article page
