We found sTn expression in CLL-BMSCs subjected to Siglec-6 Fc pull-down (with a specific band detected at ~150 kDa), with limited sTn protein detected in normal donor BMSCs, indicating that sTn on the surface of CLL-BMSCs is indeed interacting with Siglec-6 (Fig. 2c). Here, EEF1A2 is linked to B-cell chronic lymphocytic leukemia.
