CDH17 and acute myeloid leukemia: It can be seen from Table 4 that several of these stem cell regulating proteins (e.g., several extracellular matrix and adhesion molecules) were included among the 60 proteins showing undetectable levels for most patients when AML cells were cultured alone but detectable levels for most MSC cultures supplemented with the corresponding AML-CM (marked in Table 4; five extracellular matrix molecules, three enzymes important for post-transcriptional modulation of matrix molecules, three soluble cadherins).
