In parallel, mRNA expression levels of ZEB1, a key transcription factor involved in WNT signaling, stem cell maintenance and tumor\u2013stroma interactions were quantified for each sample.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The measured T1 and T2 relaxation times showed distinct profiles between tumor and non-tumor tissues.
